SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1212 PM CDT Fri Jul 29 2022 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms associated with strong winds will be possible on Saturday afternoon from parts of Oklahoma and far northeast Texas into Arkansas. ...Synopsis and Discussion... Expansive subtropical ridging is forecast to extend across the Southeast and southern Plains early Saturday morning, with another upper ridge centered near the northern CA/NV and covering much of the western CONUS. This dominance of upper ridging will lead to predominantly weak flow aloft across the majority of the CONUS. The only exceptions are early in the period across the Northeast, before the shortwave trough extended over the region moves eastward, and over the northern High Plains/northern Plains during from late Saturday afternoon into Sunday morning. This second area will be coincident with a modest shortwave trough moving through the Canadian Prairie Provinces and adjacent northern High Plains/northern Plains. Surface pattern is expected to feature a large ridge centered over the OH Valley, and modest lee troughing across the High Plains. A frontal zone will exist between the more continental air associated with the ridging and moist air mass across much of the southern Plains and Southeast. This frontal zone will be fairly broad, with some more defined portions possible due to potential augmentation via thunderstorm outflow, and is expected to act as the corridor for additional thunderstorms development during the afternoon and evening. Weakly sheared nature of the environment suggests a predominantly multicellular mode with limited updraft strength and duration. Given the very moist character of the air mass (i.e. PW values of 2-2.25"), a few isolated water-loaded downbursts capable of damaging wind gusts could occur. However, widely spaced character of events and overall marginal nature of the threat merits keeping severe wind probabilities below 5% for this outlook. ..Mosier.. 07/29/2022 Read more

See previous discussion below. ..Bentley.. 07/29/2022 .PREV DISCUSSION... /ISSUED 0200 AM CDT Fri Jul 29 2022/ ...Synopsis... A large-scale ridge will remain centered over the western CONUS, while a low-amplitude shortwave trough tracks southeastward across the northern Rockies. Beneath the upper ridge, hot/dry conditions will result in widespread 10-15 percent minimum RH east of the Cascades into the northern Rockies. The low RH, coupled with breezy northerly surface winds over southeast OR, southwest ID, and northern NV will promote elevated fire-weather conditions during the afternoon -- especially owing to highly receptive fuels over the area. In addition, large-scale ascent ahead of the shortwave trough and favorable midlevel moisture/instability will support isolated to widely scattered high-based thunderstorms over the northern Rockies. As these storms overspread a hot/dry boundary layer and critically dry fuels, lightning-induced ignitions will be possible. Farther west, upslope flow and adequate instability will also support very isolated high-based thunderstorms along the Cascades in northern CA into southern OR -- where isolated ignitions remain a concern. ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1610 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL/EASTERN VIRGINIA TO EASTERN MARYLAND/SOUTHERN DELAWARE

Isolated wind damage may occur with the strongest storms. Trends are being monitored for a possible Severe Thunderstorm Watch. DISCUSSION...Strong heating and ample insolation/boundary layer destabilization are occurring across the southern half of Virginia to the south of a southwest/northeast-oriented effective front from the central Appalachians toward the Delmarva, although buoyancy will be somewhat tempered by warm mid-level temperatures (-4 to -5C at 500mb) and poor mid-level lapse rates. Regardless, thunderstorms will develop and increase through mid-afternoon over the mountains and Blue Ridge vicinity and subsequently spread eastward. Influenced by the upper trough over the Great Lakes, a belt of moderately strong westerlies is noted, particularly with northward extent near/north of the frontal zone. This will support sustained multicells/linear segments as thunderstorms develop, and possibly even some transient supercells across east-central Virginia/eastern Maryland and Chesapeake Bay vicinity. A very moist boundary layer and steepening low-level lapse rates could yield some downbursts capable of isolated wind damage as the most probable severe hazard. ..Guyer/Grams.. 07/29/2022 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1108 AM CDT Fri Jul 29 2022 Valid 291630Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS VA AND CHESAPEAKE BAY VICINITY... ...SUMMARY... Potential for scattered damaging winds from strong to locally severe gusts is greatest across parts of Virginia and the Chesapeake Bay vicinity through early evening. ...VA and Chesapeake Bay vicinity... South of a slow-moving surface cold front, a southwest to northeast-oriented zone of differential boundary-layer heating is apparent from southwest VA to the Chesapeake. Scattered thunderstorms are expected to develop along this corridor through the afternoon. On the fringe of 35-40 kt mid-level westerlies in conjunction with a pronounced buoyancy gradient, a mix of multicell clusters and transient supercell structures are anticipated. Amid weak mid-level lapse rates, strong to locally severe gusts producing mainly tree damage should be the primary threat into early evening. ...Southern Appalachians to the Mid-South... Scattered thunderstorms are again expected along the composite outflow/differential heating corridors south of the quasi-stationary surface front. Isolated strong/damaging downbursts will be possible with water-loaded downdrafts on the fringe of modest mid-level westerlies. ...Red River Valley and TX Panhandle... Isolated to scattered thunderstorms are expected from late afternoon into mid-evening both along the surface cold front near the Red River and in a post-frontal regime over the TX Panhandle. Deep-layer shear will be weak across the region, especially for convection along the front. The latter will be compensated by a deeply mixed thermodynamic profile with hot temperatures south of the front. Isolated strong/damaging downbursts will be possible with water-loaded downdrafts. Farther west, slow-moving cells/clusters may contain a threat of both isolated, marginally severe wind/hail. ...Southern Great Basin... Around the southeast periphery of a mid-level anticyclone centered over northern CA, modest northeasterly flow of 15-20 kt will be maintained over southern NV. Boundary-layer dewpoints are generally in the low to mid 60s this morning and gradual clearing of clouds will allow strong surface heating this afternoon with MLCAPE increasing to 500-1500 J/kg. Isolated to scattered thunderstorms are expected to form by late afternoon close to the NV/UT border, and storms will subsequently spread south-southwestward on outflow into southern NV and adjacent areas of southeast CA. Given the modest buoyancy and steep low-level lapse rates, isolated severe outflow gusts up to around 70 mph will be possible with multicell clusters. ...Northern MT... A low-amplitude shortwave impulse over southeast BC will drift east across southern AB. Though moisture will be limited, deep boundary-layer mixing will occur as surface temperatures warm through the 90s. Weak ascent preceding the upper trough and weak low-level convergence along a surface trough will support isolated to scattered thunderstorms later this afternoon. Though low to mid-level flow will remain weak, deep inverted-v profiles will favor isolated strong outflow gusts of 50-60 mph. ...NE Panhandle vicinity... Isolated thunderstorms may develop along the northern periphery of the High Plains moisture plume during the late afternoon/early evening. Adequate veering of the wind profile with height (weak low-level southerlies to modest mid-level northwesterlies) will support a short-duration and very isolated threat for marginally severe hail/wind. ..Grams/Lyons.. 07/29/2022 Read more

Long Creek Fire (Wildfire)

3 years ago
 The Long Creek Fire began at about 1245pm on Wednesday, July 27. The fire began due to a spark created by fire equipment. By 4pm the fire had grown to about 150 acres with 0% containment. The fire had a very high potential for growth and was burning in thick brush. There was no threat to structures. Dozers finished constructing line along the fire's perimeter at around 630pm. At that time, the fire was estimated to be 215 acres in size and 50% contained. Engines continued to mop up residual heat along the fire's perimeter until the fire was determined to be 90% contained. Fire crews will return Thursday morning to patrol the fire area and mop up any residual heat along the fire's

Tropical Storm Georgette Forecast Discussion Number 9

Issued at 800 AM PDT Fri Jul 29 2022 715 WTPZ43 KNHC 291438 TCDEP3 Tropical Storm Georgette Discussion Number 9 NWS National Hurricane Center Miami FL EP082022 800 AM PDT Fri Jul 29 2022 GOES-17 Proxy-Vis and enhanced IR imagery show that Georgette's cloud pattern has become more symmetric with colder -77C inner core cloud tops. An earlier AMSR2 revealed an eye-like feature in the lower frequency band and a well-developed rain band in the north part of the cyclone. The eye feature, however, was not evident in the infrared presentation. Although the Dvorak subjective T-numbers from TAFB and SAB haven't changed; the initial intensity is increased to 50 kt in deference to the microwave image. The global models and the statistical intensity guidance indicate that the easterly shear will increase within 24 hours, causing Georgette to weaken slowly. However, due to Georgette's compact size, intensity fluctuations are possible in the short term. The latest GFS run shows that Georgette could hang on a little longer than the NHC forecast indicates, possibly as a post-tropical cyclone. Therefore, adjusting the forecast may be deemed necessary to extend the cyclone's life in subsequent advisories. The official forecast is very close to the HCCA and IVCN intensity aids. Georgette's initial motion is estimated to be just a bit south of due west or 260/11 kt. A mid-tropospheric ridge stretching east-northeast to west-southwest should steer the small cyclone west to west-southwestward during the next 48 hours. Afterward, a reduction in forward speed along with a turn toward the northeast is expected in response to larger Frank weakening the ridge and disrupting the steering flow while passing to the northeast of Georgette. Although the ECMWF global has been the best performer in the eastern Pacific this season with respect to forecast track, the model continues to initialize poorly the compact TC indicating a significantly weaker system while remaining the left tracker outlier. The GFS, however, now has a more accurate depiction of the cyclone's size and vertical depth and shows a more direct response to Frank's larger wind field. There still is quite a bit of uncertainty in Georgette's future track as evident by the larger than usual guidance spread, particularly after the northeast turn. Consequently, this is a low confidence forecast. The NHC forecast is similar to the previous advisory through 48 hours, but has been adjusted to the left beyond that point to agree more with the HCCA and GEFS/EPS ensemble member solutions.

Tropical Storm Frank Forecast Discussion Number 14

3 years ago
Issued at 900 AM MDT Fri Jul 29 2022 000 WTPZ42 KNHC 291437 TCDEP2 Tropical Storm Frank Discussion Number 14 NWS National Hurricane Center Miami FL EP072022 900 AM MDT Fri Jul 29 2022 In infrared imagery, Frank's appearance has not changed much since the last advisory. While the system shows a large curved convective band that wraps a little more than three-quarters of the way around the center, the central deep convection is a bit ragged, possibly due to dry air entrainment from the northwest. However, recent 37 GHz microwave data shows the cyclone has developed a good low-level structure, with a ring of shallow to moderate convection surrounding a 40 n mi wide developing eye. Satellite intensity estimates have changed little since the previous advisory, so the initial intensity remains 55 kt. Frank will be in an environment of light vertical shear and over sea surface temperatures of 28-29C for the next 36 h, and the inner-core structure seen in the microwave imagery favors a faster rate of strengthening. The one current negative factor is the dry air entrainment that is causing the inner core deep convection to sputter. The intensity forecast assumes strengthening will resume as the deep convection will becomes persistent, and it follows the trend of the intensity guidance in calling for a peak intensity of 90 kt in 36 h. After that time, Frank should move over progressively cooler SSTs, with the system reaching 21C water by 120 h. This should cause steady to rapid weakening, and Frank is forecast to become a remnant low by the end of the forecast period. The initial motion is now 300/10 kt. Frank is moving along the southwest side of the subtropical ridge over northwestern Mexico, and it should move generally northwestward during the forecast period toward a developing break in the ridge west of California. The track guidance is in good agreement with this scenario and has changed little since the previous advisory. Thus, the new forecast track is an update of the previous forecast. It again should be noted that Frank and Tropical Storm Georgette are expected to come close enough to one another for some interaction. Frank will be the larger and dominant system during this interaction, and Georgette will have little impact on the track or intensity of Frank.
