MD 2171 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN NEW MEXICO INTO THE OKLAHOMA AND TEXAS PANHANDLES
Mesoscale Discussion 2171 NWS Storm Prediction Center Norman OK 0443 PM CDT Thu Sep 21 2023 Areas affected...Eastern New Mexico into the Oklahoma and Texas Panhandles Concerning...Severe potential...Watch unlikely Valid 212143Z - 212345Z Probability of Watch Issuance...20 percent SUMMARY...Thunderstorms will increase in coverage over the next few hours, and a few strong to severe storms appear likely. Severe wind and large hail will be the primary threats, but confidence in the coverage/duration of this threat is limited and watch issuance is not anticipated. DISCUSSION...Convective initiation is well underway across central to eastern NM within the left-exit region of an approaching upper jet. This high-based activity is developing on the western fringe of the low-level moisture plume over the Plains with dewpoints in the upper 40s to low 50s and dewpoint depressions upwards of 40-50 F noted in latest surface obs. Although buoyancy profiles are somewhat meager (MLCAPE between 500-1000 J/kg), the deeply-mixed low-level thermodynamic profile is conducive for strong to severe downburst winds. Combined with weak low-level flow, this may favor undercutting outflows and storm clustering with time, which limits confidence in the duration of any particular strong/severe storm. However, strong speed shear in the 0-6 km layer will support initial cell organization with an attendant hail risk. The expectation over the next several hours is for additional storms to develop across eastern NM, slowly intensifying (with perhaps some clustering/upscale growth) as they migrate into the TX/OK Panhandles where low-level moisture improves. However, increasing inhibition closer to the TX/western OK border and the onset of nocturnal cooling later this evening may limit the eastward extent of the threat. ..Moore/Thompson.. 09/21/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0359 PM CDT Thu Sep 21 2023 Valid 231200Z - 291200Z ...Day 3/Saturday... On the backside of a midlevel low tracking northeastward across the northern Plains, strong deep-layer northwesterly flow will overspread the northern/central High Plains. As a result, 25+ mph sustained west-northwesterly surface winds (with higher gusts) are expected across portions of southern WY, western NE, and far northeastern CO. While these winds could briefly overlap 20-30 percent RH over the area, marginal fuels should generally limit the fire-weather risk. ...Days 4-5/Sunday-Monday... Southwesterly midlevel flow will gradually strengthen across the Northwest on Days 4-5/Sunday-Monday, favoring breezy southwesterly surface winds across portions of northeastern CA, northwestern NV, and far southeastern OR -- where 15-20 percent RH is possible. With that said, fuels are generally unsupportive of large fires over these areas -- precluding Critical probabilities. ...Days 6-8/Tuesday-Thursday... The potential for dry/breezy conditions should focus over portions of the Southwest and Great Basin late in the extended forecast period, and potentially over the High Plains depending on moisture return. However, additional rainfall over already marginal fuels across these areas cast uncertainty on the fire-weather risk. ..Weinman.. 09/21/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

Tropical Storm Kenneth Forecast Discussion Number 10

1 year 9 months ago
Issued at 200 PM PDT Thu Sep 21 2023 000 WTPZ43 KNHC 212040 TCDEP3 Tropical Storm Kenneth Discussion Number 10 NWS National Hurricane Center Miami FL EP132023 200 PM PDT Thu Sep 21 2023 Kenneth is a sheared tropical cyclone. The small area of active convection associated with the storm has been displaced over 90 n mi from its exposed low-level center by southwesterly shear. This deteriorating satellite presentation has caused the intensity estimates to decrease today. Based on a blend of the latest objective and subjective Dvorak estimates, the initial intensity is lowered to 35 kt. Recent satellite images indicate Kenneth has begun its northward turn, and the initial motion is north-northwestward at 330/6 kt. A generally northward motion should continue for the next couple of days as the system moves within the flow between a mid-level trough to the northwest and a mid-level ridge over central Mexico. There were no major changes to the track guidance this cycle, and the latest NHC forecast is similar to the previous prediction. While simulated satellite imagery from the global models suggest Kenneth could produce intermittent bursts of sheared convection during the next day or so, the environmental conditions (stronger shear, progressively cooler SSTs, and a drier and more stable airmass) are not conducive for sustained convection going forward. Based on these factors and recent satellite trends, this forecast shows additional weakening with post-tropical/remnant low status in 24 h.

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0249 PM CDT Thu Sep 21 2023 Valid 212000Z - 221200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF WESTERN KS AND WESTERN/CENTRAL NE...AND OVER PARTS OF SOUTHERN OK AND NORTH TX... ...SUMMARY... Widely scattered strong to severe thunderstorms are possible this afternoon into tonight across parts of the southern and central Plains. ...20Z Update... ...NE/KS... Recent surface analysis places a low near the CO/NE/KS border intersection, with a dryline extending southward across western KS. As mentioned in recently issued MCD #2168, storm initiation appears probable in the next couple of hours across parts of southwestern Nebraska. The deepening surface low is supporting robust southeasterly flow and strong low-level shear. Moderate westerly flow exists atop this low-level southeasterly flow, supporting 30 to 40 kt of effective bulk shear. Strong buoyancy has also developed ahead of the dryline, with recent mesoanalysis estimating 1500 to 2500 J/kg MLCAPE across western KS and western/central NE. The overall environment supports supercells capable of all severe hazards including large to very-large (1-3 in.) hail, severe wind gusts (60-70 mph), and tornadoes. The tornado threat will generally be maximized near the warm front where surface winds remain more backed. ...Southern OK/North TX... Despite widespread clouds, temperatures have reached the upper 80s/low 90s across much of the region. Dewpoints are in the upper 60s/low 70s, and this combination of temperatures and dewpoints is supporting strong buoyancy. Recent mesoanalysis estimates MLCAPE is around 2000-2500 J/kg. Vertical shear is modest, but sufficient for some updraft organization. As such, a few strong to severe thunderstorms remain possible, with large hail and damaging gusts as the primary threats. ..Mosier.. 09/21/2023 .PREV DISCUSSION... /ISSUED 1112 AM CDT Thu Sep 21 2023/ ...Central and Southern Plains... Morning water vapor imagery shows a subtle shortwave trough crossing the Rockies of central CO. This feature will move eastward and provide weak large scale ascent across much of the central Plains this afternoon and evening. Morning model solutions are diverse in placement/timing of thunderstorm activity, but generally show a larger envelope of potential risk. Therefore have expanded the MRGL to include much more of the central and southern Plains. ...NE/KS... A rather pronounced surface dryline is expected to develop later today from western NE southward into western KS, with dewpoints in the 60s and MLCAPE values of over 2500 J/kg to the east of the boundary. Given the weak forcing and some cap, the areal coverage of convective initiation is uncertain. However, any storm that forms along this axis will have a conditional threat of very large hail and a tornado or two. These storms may persist for several hours after dark and track eastward into parts of north central KS and central NE. ...OK/TX... A weak sub-tropical shortwave trough is moving into west TX. Lift ahead of this feature is resulting in a large region of accas and a few showers and thunderstorms moving into southwest OK/northwest TX. Continued daytime heating is expected to lead to convective intensification by late afternoon across north TX and southern OK. The strongest cells in this area may produce hail and gusty winds for a few hours into this evening. ...Eastern NC... The outer bands of the strengthening tropical system off the southeast Atlantic coast are forecast to still be well offshore by Fri/12z. Therefore will defer any increasing tornado risk to the Day2 period. Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0207 PM CDT Thu Sep 21 2023 Valid 221200Z - 231200Z The latest fuels information suggests that fine fuels have dried sufficiently over portions of the mountains/I-25 corridor in southern Colorado to support some fire potential. Given the expectation for sustained southwesterly surface winds of 15-25 mph (with higher gusts) and around 10 percent RH, the Elevated highlights were expanded westward into this area. Over the southeast Colorado plains, the Elevated highlights were trimmed as the latest guidance suggests sustained surface winds will be too weak for an appreciable fire-weather risk. For additional details, see the previous discussion below. ..Weinman.. 09/21/2023 .PREV DISCUSSION... /ISSUED 0157 AM CDT Thu Sep 21 2023/ ...Synopsis... An upper low across eastern Oregon will start to fill during the day Friday and eventually become a negatively tilted open wave across the central/northern Rockies. As this upper-level pattern evolves, lee troughing is expected, which will bring some breezy conditions from the Southwest into the central Rockies and also the central High Plains and the central Plains. Farther west in Arizona and Utah, fuels are too moist to support fire spread. However, in the plains across southeast Colorado and northeast New Mexico and vicinity, some drier fuels are present. These fuels will likely dry further with single-digit relative humidity. Therefore, an Elevated area has been added for portions of the central High Plains for Friday. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

AMENDED TO ADD SEVERE PROBABILITIES OVER THE COASTAL MID-ATLANTIC ...SUMMARY... Severe thunderstorms are possible on Saturday across parts of the central and southern Plains into Iowa and Missouri. ...Coastal Mid-Atlantic... Recently issued track of Potential Tropical Cyclone 16 brings it onshore over coastal NC early Saturday morning, and then northward into the Chesapeake Bay by Saturday evening. Recent guidance suggests the warm sector to the north and east of the system's center should penetrate far enough inland to support modest buoyancy and deeper convective cores. Given the strong low to mid-level wind fields, any updrafts that are able to deepen and mature could produce tornadoes. Mesoscale details, in particular how much buoyancy develops inland, remain uncertain enough to introducing only a Marginal/Level 2 risk with this amendment. -- PREVIOUS DISCUSSION -- ...Great Plains into parts of MN/IA/MO... A seasonably strong mid/upper-level cyclone is forecast to move eastward across SD on Saturday. The primary surface low attendant to this mid/upper cyclone is forecast to move from the central Plains into the Dakotas as the system begins to occlude, while secondary surface low development is possible along the trailing front across the southern Plains. Moderate to locally strong buoyancy is expected to develop across a broad area of the Great Plains on Saturday, east of the cold front and outside of any areas where outflow persists from morning convection. One notable midlevel jet maximum is forecast to move from the central Plains into the Dakotas, while a southern-stream jet maximum will begin to impinge upon parts of the southern Plains. Organized convection will be possible Saturday into Saturday night across a broad region from the Great Plains into parts of MN/IA/MO, with a mixture of supercells and organized clusters possible along/east of a cold front. Initial development is most likely closer to the mid/upper-level low across the central/northern Plains, with storm development into parts of the southern Plains expected by early Saturday evening. All severe hazards will be possible, though primary storm mode and evolution of mesoscale details remain uncertain at this forecast range. ...Eastern NC into the Mid Atlantic... A surface low is forecast to move from near or just offshore of eastern NC into parts of the Mid Atlantic on Saturday. Depending on the westward extent of the track, richer low-level moisture may spread into coastal areas of the Mid Atlantic region, potentially accompanied by increasing low-level flow/shear and some threat for a brief tornado or two. Depending on the ultimate track and intensity of this system, severe probabilities may eventually be needed for some part of this region. ..Mosier/Dean.. 09/21/2023 Read more

Drought watch, warning in Maryland

1 year 9 months ago
The Maryland Department of the Environment put some northern counties in a drought warning rather than a drought watch. Counties in a drought warning include Baltimore, Carroll, Cecil, Frederick, Harford, Howard and Montgomery counties, except those areas served by Baltimore City or Washington Suburban Sanitary Commission public water systems. The shift to drought warning status was due to lower-than-normal stream flows and groundwater levels for this time of year. Washington, Allegany and Garret counties remained in a drought watch.

Tropical Storm Kenneth Forecast Discussion Number 6

1 year 9 months ago
Issued at 200 PM PDT Wed Sep 20 2023 870 WTPZ43 KNHC 202038 TCDEP3 Tropical Storm Kenneth Discussion Number 6 NWS National Hurricane Center Miami FL EP132023 200 PM PDT Wed Sep 20 2023 Kenneth's cloud pattern has not changed appreciably during the last 6 hours. The average of the latest TAFB and SAB Dvorak numbers is 45 kt. Most of the objective intensity estimates are a bit lower. Based on the above data, the initial intensity is maintained at 45 kt for this advisory. The center of Kenneth is estimated to be near the southern edge of the central dense overcast. However, the current position is quite uncertain. The initial motion is estimated at 290/9 kt. A turn to the northwest and north-northwest is expected on Thursday between a subtropical high centered over northwestern Mexico and a potent mid- to upper-level trough to the northwest of Kenneth. The track forecast has been adjusted a bit to the north of the previous NHC track prediction, but not as far north as the latest consensus models. Kenneth is currently located in an environment that is favorable enough for it to at least maintain its intensity over the next 12-24 hours. However, a more stable air mass is located just to the north and northwest of the cyclone, as evidenced by scattered low stratus clouds seen on GOES-18 satellite imagery, indicative of a marine boundary layer. As Kenneth approaches the mid- to upper-level trough over the next couple of days, strong southwesterly wind shear will increasingly encroach on Kenneth. Kenneth will also cross the 26C isotherm about the same time the shear ramps up Thursday evening. Therefore, steady weakening is forecast, and Kenneth should become a remnant low Friday night or Saturday. The latest NHC intensity forecast is similar to the previous one and is near the middle of the intensity consensus aids.
