Severe Storms

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1152 PM CST Sat Mar 08 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across portions of the Florida Peninsula and parts of the Carolinas on Monday. Severe storms are not expected. ...Synopsis... An upper low over AL Monday morning will shift east, moving offshore over the Gulf Stream by evening. At the surface, a low near the GA coast will deepen as it shifts northeast over the Atlantic, and a trailing cold front will develop southward across the FL Peninsula. Isolated thunderstorms may be ongoing near the cold front Monday morning and continue sporadically into the afternoon with southward extent. Deep-layer flow will be moderately strong, but mostly parallel to the cold front. Meanwhile, warm midlevel temperatures across FL will result in modest midlevel lapse rates, limiting instability (generally less than 750 J/kg MLCAPE). This will largely limit severe potential, though a brief strong storm or two could produce gusty winds. Further north, isolated thunderstorms are possible across parts of the Carolinas closer to the surface and upper low. Cold temperatures aloft will result in steep midlevel lapse rates and MUCAPE around 200-400 J/kg. Severe storms are not expected but a couple instances of small hail will be possible with mainly elevated convection through the afternoon. ..Leitman.. 03/09/2025 Read more

Isolated severe storms will be possible tonight from parts of the southeast Texas eastward into the Gulf Coast states. ...Sabine and Lower Mississippi Valleys/Central and Eastern Gulf Coast Vicinity... The latest water vapor imagery has a mid-level low over the southern High Plains with southwest flow from southwest Texas into the Ark-La-Tex. An 80 to 100 knot mid-level jet is analyzed by the RAP over central Texas. A cluster of storms has developed near the exit region of this feature in southeast Texas. The storms are located just ahead of a cold front, along inverted trough in the Texas Coastal Plain, where surface dewpoints are mostly in the 65 to 70 F range. A small pocket of moderate instability, with MLCAPE in the 1000 to 1500 J/kg range, is analyzed by the RAP in the vicinity of Houston. The ongoing storms are located along the northern edge of this stronger instability. The WSR-88D VWP near Houston has 0-6 km shear around 70 knots. The instability and shear will be sufficient for a severe threat this evening. The storms should eventually affect parts of the lower Mississippi Valley later this evening into the overnight. Further to the east, a small area of thunderstorms has developed near the southeastern most point of Louisiana, with other storms located eastward into the northeastern Gulf. These storms will continue moving northeastward into the central and eastern Gulf Coast tonight. Low-level moisture advection, associated with the approaching mid-level system, will contribute to a gradual increase in instability across the central and eastern Gulf Coast. For this reason, a marginal severe threat is expected to develop tonight from southern Mississippi eastward into southern Alabama, northern Florida and far southern Georgia. The primary threat will be for isolated severe gusts. A conditional threat for a brief tornado is also expected. ..Broyles.. 03/09/2025 Read more

MD 0157 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEAST TEXAS
Mesoscale Discussion 0157 NWS Storm Prediction Center Norman OK 0323 PM CST Sat Mar 08 2025 Areas affected...southeast Texas Concerning...Severe potential...Watch unlikely Valid 082123Z - 090000Z Probability of Watch Issuance...20 percent SUMMARY...A few strong storms are expected to develop over the next few hours, with isolated large hail or gusty winds possible. DISCUSSION...A weak surface low is present south of the Austin TX area, where a cold front approaching from the west is intersecting the southward surging boundary. The eastern portion of the boundary extends across the Sabine River and into southern LA, with substantial clouds and cooler temperatures within that zone. Southerly winds across the warm sector have led to around 1500 J/kg MLCAPE, with temperatures in the 80s F and dewpoints mixed into the upper 60s F. Deep-layer shear is robust at over 60 kt, with lengthy hodographs. Low-level winds are relatively weak, but modest SRH values exist near the warm advection zone east of Houston. Visible imagery shows deepening CU fields around Houston, indicative of a moist deepening boundary layer, and showers are beginning to show on radar. As the cold front pushes into the area and interacts with the unstable air mass near peak heating, at least isolated cells are anticipated. Good lapse rates aloft and strong deep shear will support hail. A conditional damaging wind or even brief tornado risk could potentially occur with any storm that remains situated along the cold front/warm front intersection north/east of Houston, but any such threat should remain localized. ..Jewell/Bunting.. 03/08/2025 ...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 0408 PM CST Sat Mar 08 2025 Valid 101200Z - 161200Z A very active fire-weather pattern is expected throughout the extended forecast period across much of the southern High Plains. Confidence in the development of widespread critical conditions is highest on Day 5/Wednesday and Day 7/Friday. ...Day 5/Wednesday - Southern High Plains... The first low-latitude midlevel shortwave trough will cross the southern Rockies on Day 5/Wednesday, while a related surface cyclone deepens over the central Plains. South of the cyclone, very strong/gusty westerly surface winds and low RH will develop across the southern High Plains, favoring critical fire-weather conditions. ...Day 7/Friday - Southern High Plains... Within the base of a highly amplified large-scale trough tracking eastward across the West, a 90+ kt midlevel jet streak will overspread the southern and central Plains. In response, a surface cyclone will rapidly deepen over the central High Plains. This will result in very strong/gusty west-southwesterly surface winds and low RH across the southern High Plains, where high-end critical conditions are expected. Strong winds and low RH will likely extend farther northeast into the central Plains, and depending on fuel trends over the next several days, 70-percent Critical probabilities may need to be expanded into this region. ..Weinman.. 03/08/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
