MD 1619 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL/EAST NC...FAR SOUTH-CENTRAL/SOUTHEAST VA
Mesoscale Discussion 1619 NWS Storm Prediction Center Norman OK 1138 AM CDT Sun Jul 31 2022 Areas affected...Central/East NC...Far South-Central/Southeast VA Concerning...Severe potential...Watch unlikely Valid 311638Z - 311915Z Probability of Watch Issuance...20 percent SUMMARY...Multicell thunderstorms capable of damaging wind gusts will persist across the region through the afternoon. Additionally, a supercell or two is possible later this afternoon, with an attendant risk of damaging wind gust and/or a brief tornado. DISCUSSION...The air mass across north-central/northeast NC and adjacent portions of far south-central/southeast VA has quickly destabilized amid filtered diurnal heating and ample low-level moisture. Thunderstorm coverage is expected to gradually increase over the next few hours, as modest low-level convergence persists near and south of the wavy warm front extending from south-central VA into far northeast NC. Much of this thunderstorm activity will occur south of the stronger mid-level flow, limiting the deep-layer vertical shear and likely leading to a predominantly multicellular, outflow-dominant storm mode. Primary severe risk with any of these storms is water-loaded downbursts. Later this afternoon, ascent may be augmented slightly by the shortwave trough moving through the Upper OH Valley. This shortwave will also contribute to a modest increase in the mid-level flow. While still favorable mostly multicells, these condition could also support a supercell or two. Primary risk would continue to be damaging wind gust, although a brief tornado or two could also occur. ..Mosier/Grams.. 07/31/2022 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1126 AM CDT Sun Jul 31 2022 Valid 311700Z - 011200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN OREGON INTO EXTREME NORTHERN CALIFORNIA... Only minor modifications were made to the ongoing IsoDryT delineation, primarily to trim the western edge where fuels are not as favorable. ..Bentley.. 07/31/2022 .PREV DISCUSSION... /ISSUED 0222 AM CDT Sun Jul 31 2022/ ...Synopsis... Upper ridging will remain in place across the western U.S. today while a mid-level trough ejects into the Plains states during the afternoon. Downslope flow along the higher terrain in western Montana and modest surface lee troughing across the northern Plains may support at least locally dry and windy conditions for a few hours. The bigger concern for wildfire-spread potential today exists across the Pacific Northwest. Modest deep-layer ascent with passing subtle mid-level impulses will work in tandem with afternoon peak heating to support the initiation of scattered high-based thunderstorms across portions of the Pacific Northwest, where fuels have recently become highly receptive to fire spread (based on the latest observations). The previous day's storms may have slightly dampened fuels locally. However, the relatively higher number of thunderstorm expected today, combined with the critically dry fuels (especially in lower-terrain areas) necessitates the addition of scattered dry thunderstorm highlights. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1116 AM CDT Sun Jul 31 2022 Valid 311630Z - 011200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS EAST-CENTRAL/SOUTHEAST MN INTO WEST-CENTRAL WI... ...SUMMARY... A tornado or two, scattered damaging winds, and isolated severe hail are most likely across a portion of the Upper Mississippi Valley between about 5 to 9 PM CDT. ...Synopsis... A low-amplitude shortwave trough centered on the MB/ND border area will progress east-southeast into the western Great Lakes region tonight. Associated surface cold front over the eastern Dakotas will similarly push east-southeast across the Upper MS Valley through this evening. ...Upper MS Valley... Low-level warm-advection-driven convection is ongoing across south-central MN to northwest IA, but decaying ahead of the cold front. Stronger surface heating and greater boundary-layer moisture in the wake of this activity will support a confined plume of moderate buoyancy with MLCAPE increasing to 1500-2000 J/kg by 21-00Z. Initial surface-based thunderstorm development is expected along the northern periphery of the buoyancy gradient in northwest to north-central MN. Convection will likely build south along the front through central to east-central MN during the early evening, with lower confidence in southern extent towards the IA border. Surface temperature-dew point spreads will be marginally large initially, but favorable low-level hodograph curvature/SRH will be sufficient for a threat of a tornado or two. Otherwise, around 30-35 kt effective bulk shear should yield a mixed cluster/embedded supercell mode, with the latter tending to be favored farther south where shear is slightly stronger and convection should be more semi-discrete. Damaging winds should be somewhat more favored in terms of coverage, but isolated severe hail is anticipated as well. Convection will likely diminish tonight as it spreads east of the confined surface-based buoyancy plume deeper into WI. ...NE/IA... A conditional supercell threat will exist across portions of northern to western IA along the surface cold front centered on early evening, in the wake of decaying elevated activity approaching the region. Isolated thunderstorms are more probable into the southwest NE area where MLCIN will be minimal at peak heating, along the western extent of the central Great Plains buoyancy plume. Weaker deep-layer shear should tend to favor a more marginal intensity threat this far west. ...NC/southern VA... A weak and wavy surface warm front has drifted north into far southwest VA and northeast NC, in advance of a low-amplitude shortwave impulse over the Upper OH Valley. The southern fringe of modestly stronger mid-level westerlies (represented by effective bulk shear near 30 kt) will overlie the baroclinic zone, where there will be some enhancement to low-level hodograph curvature (0-1 km SRH around 100 m2/s2). Despite poor mid-level lapse rates, a mix of multicell clusters and transient supercells are expected across the baroclinic zone through about dusk. A brief weak tornado and isolated damaging wind gusts in water-loaded downdrafts will be possible. ...Southern AZ... The next perturbation within the monsoonal moisture plume is aiding morning thunderstorms over a portion of northwest Sonora and will likely yield a period of mid-level drying across southeast AZ in its wake. The midlevel drying and reduction in clouds will aid surface heating, but also casts some doubt on how widespread convection will be across the higher terrain in southeast AZ this afternoon. 15-20 kt southeasterly mid-level steering flow will support potential for isolated cells and small clusters to spread across the lower deserts of south-central AZ through about dusk with isolated severe wind gusts possible. ...Lower CO Valley to OR... Very isolated severe wind gusts are possible in pulse microbursts, but overall coverage is anticipated to be less than 5 percent over such a large swath around the Great Basin mid-level anticyclone. ..Grams/Lyons.. 07/31/2022 Read more

Brook Mole Fire (Wildfire)

3 years ago
The Brook Mole Fire began at about 2:20pm on Friday, July 29. Fire personnel estimated the fire to be about 300 acres and 0% contained upon arrival. The fire burned on both sides of Brook Mole Road. Fire crews successfully held the fire east of Eureka School Road with the assistance of multiple aerial resources. Dozers secured the fire's perimeter and engines "mopped up" pockets of residual heat along the fire's perimeter. Local crews remained on scene overnight to monitor the fire. Additional crews returned in the morning to mop up remaining heat along the fire's perimeter and patrol the fire line.  The fire received some rain Friday night and into Saturday morning. As of Saturday afternoon, the fire is 100%

Hurricane Frank Forecast Discussion Number 22

3 years ago
Issued at 800 AM PDT Sun Jul 31 2022 000 WTPZ42 KNHC 311439 TCDEP2 Hurricane Frank Discussion Number 22 NWS National Hurricane Center Miami FL EP072022 800 AM PDT Sun Jul 31 2022 An 0933 UTC AMSR2 microwave overpass revealed the fragments of a small inner eye and a much larger 60 to 75 n-mi-wide eye. Since that time, the cloud tops have generally warmed with a small CDO feature remaining. Frank's outflow is still well established owing to the low vertical wind shear conditions. Objective and subjective Dvorak intensity estimates range between 65 and 77 kt, so the initial intensity has been lowered to 75 kt for this advisory. Frank has crossed the 26 degree Celsius isotherm and will be moving over progressively cooler waters during the next few days. In addition, the storm will be entering a drier and more stable environment. Thus, steady weakening is expected, and Frank is forecast to become a post-tropical cyclone within 72 hours, and dissipate by the end of the period. The NHC intensity forecast follows the HCCA and IVCN consensus aids closely and is essentially an update of the previous advisory. Frank is moving northwestward or 315/10 kt. The cyclone should move on a general northwestward track over the next couple of days around the southwestern portion of a mid-level ridge. After that time, a weaker and more shallow system is predicted to decelerate and turn north-northwest to northward within the low-level flow. The updated NHC track forecast is in good agreement with the latest consensus models and is very close to the previous official forecast.

Tropical Storm Georgette Forecast Discussion Number 17

3 years ago
Issued at 800 AM PDT Sun Jul 31 2022 000 WTPZ43 KNHC 311437 TCDEP3 Tropical Storm Georgette Discussion Number 17 NWS National Hurricane Center Miami FL EP082022 800 AM PDT Sun Jul 31 2022 Deep convection waned through the overnight hours over the center of Georgette. However, over the past couple of hours some regeneration of convection has occurred over the cyclone's southern semicircle. There has been no new satellite wind data over the storm since early this morning, but the degradation of Georgette's appearance suggests continued weakening has occurred since the previous advisory. A blend of the latest CI values from TAFB, SAB, and the UW-CIMSS ADT yields an intensity of 35 kt, which will be the initial advisory intensity. Georgette is moving slowly westward, or 260/5 kt, to the south of a mid-tropospheric ridge. The portion of the ridge to the north of the cyclone should weaken through early this week as Hurricane Frank passes well to the north. As a result, Georgette should continue to slow its forward motion and then begin drifting northward early this week toward the temporary weakness in the ridge carved out by Frank. By mid-week, the ridge is forecast to re-strengthen, forcing the cyclone on a more westward track. The latest NHC forecast track is very similar to the previous one, as the track guidance has changed little since that time. The outflow from the large circulation of Frank continues to produce some strong easterly shear across Georgette that is causing it to struggle maintaining persistent deep convection. This shear is forecast to continue for the next couple of days. Therefore, Georgette is expected to weaken a little more today and be a tropical depression through early this week. There is some possiblity that the shear will decrease before Georgette passes over cooler waters, and some flucuation in intensity is possible before Georgette becomes a remnant low late in the period. The latest NHC intensity forecast was adjusted slightly lower than the previous one, and is close to the various multi-model intensity consensus solutions.
