Severe Storms

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1030 AM CST Thu Dec 15 2022 Valid 161200Z - 171200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast on Friday. ...Synopsis and Discussion... Generally cool and stable conditions will exist Friday over much of the CONUS as an upper low remains over the Upper Midwest and Great Lakes. Broad mid-level cyclonic flow will exist from the Rockies to the East Coast, with strong westerlies aloft over the Southeast. At the surface, high pressure will be present over much of the West, with a ridge stretching east across the southern Plains and Southeast. The only area of appreciable thunderstorm potential will be over parts of south Florida and the Keys near the tail end of a stalling front. Here, modest instability along with weak surface convergence may foster isolated thunderstorms. Severe convection appears unlikely. ..Gleason.. 12/15/2022 Read more

MD 2046 CONCERNING WINTER MIXED PRECIPITATION FOR PORTIONS OF EASTERN PENNSYLVANIA...SOUTHERN NEW YORK...AND FAR NORTHWEST NEW JERSEY
Mesoscale Discussion 2046 NWS Storm Prediction Center Norman OK 1024 AM CST Thu Dec 15 2022 Areas affected...Portions of eastern Pennsylvania...southern New York...and far northwest New Jersey Concerning...Winter mixed precipitation Valid 151624Z - 152030Z SUMMARY...Snow, sleet, and freezing rain will transition to mostly snow this afternoon across portions of the central Appalachians. DISCUSSION...Freezing rain has been observed for much of the morning across eastern Pennsylvania and vicinity. In this region, a large warm conveyor belt, associated with a large upper low across the Midwest has overspread cold air damming east of the Appalachians. However, temperatures aloft are not that warm across the region with RAP forecast soundings showing a warm nose around 1 to 2 C across eastern Pennsylvania. Therefore, the entire profile should drop below freezing in the next several hours as temperatures cool aloft and a surface low currently over South Carolina deepens and moves up the coast. Moderate, to locally heavy snow is expected once this occurs with snowfall rates up to 1 inch per hour. ..Bentley.. 12/15/2022 ...Please see www.spc.noaa.gov for graphic product...

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1015 AM CST Thu Dec 15 2022 Valid 151630Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON OVER PARTS OF CENTRAL FLORIDA... ...SUMMARY... A few tornadoes and scattered damaging thunderstorm winds will be possible today over parts of the Florida Peninsula. ...FL... A large upper low is in place today over much of the CONUS, with the primary surface cold front sagging southward into the FL peninsula and southeast states. A line of intense thunderstorms along/ahead of the front will move into central FL this afternoon, where rich low level moisture and considerable low-level vertical shear is present. Several of these storms have shown supercell/bowing structures offshore, and also as they have moved inland this morning. This scenario will likely continue through at least early afternoon, before a gradual weakening of wind fields diminishes the severe threat. Please refer to MCD #2045 for further short-term details. ...GA/SC/NC... The main surface cold front extends from the western Carolinas into east GA. Southerly low-level winds ahead of the front will maintain dewpoints in the 50s and 60s, along with marginal CAPE. While the thermodynamic environment appears weak, very strong low and mid-level winds/shear suggest a risk of brief organization of any deep convection that can be maintained. Locally gusty winds or a brief tornado cannot be ruled out until the front moves offshore late this afternoon or early evening. ..Hart/Bentley.. 12/15/2022 Read more

No changes to the ongoing forecast. ..Wendt.. 12/15/2022 .PREV DISCUSSION... /ISSUED 0153 AM CST Thu Dec 15 2022/ ...Synopsis... In the wake of the stalled upper-level cyclone over the Midwest, a cold front is forecast to move south over much of the western US and Plains Thursday. Surface high pressure behind the front will keep winds light and temperatures much colder through the remainder of the forecast period. Fuels have also moderated, suggesting low potential for large fire spread. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 2032 CONCERNING TORNADO WATCH 588... FOR SOUTHERN MS...SOUTHWEST AL...EASTERN LA
Mesoscale Discussion 2032 NWS Storm Prediction Center Norman OK 0120 PM CST Wed Dec 14 2022 Areas affected...Southern MS...Southwest AL...Eastern LA Concerning...Tornado Watch 588... Valid 141920Z - 142045Z The severe weather threat for Tornado Watch 588 continues. SUMMARY...The threat for strong, long-track tornadoes continues. DISCUSSION...Regional radar imagery continues to show numerous discrete supercells, including a few which have rotational velocity around 40 to 50 kt. The overall environment remain very conducive to tornadic supercells with ample low-level moisture and buoyancy in the presence of strong low to mid-level flow. Recent KLIX VAD data shows increasing winds in the 1-2 km layer. This increase is likely due to a mesoscale low-level jet, which is expected to move northeastward across far southern MS and into southwest AL over the next several hours. Attendant strengthening of the low-level shear within this corridor could augment the already favorable conditions. Surface observations also numerous gusts of 25 to 30 kt across southeast LA. Additionally, ongoing storms will likely strengthen as they approach and interact the warm front, which now extends from about 50 miles northwest of MEI southeastward to south of GZH in southern AL. In all, the threat for strong, long-track tornadoes will continue for at least the next few hours across eastern LA and southern MS, eventually reaching southwest AL later this afternoon/early this evening. ..Mosier/Hart.. 12/14/2022 ...Please see www.spc.noaa.gov for graphic product...

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1124 AM CST Wed Dec 14 2022 Valid 151200Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF FLORIDA...COASTAL/SOUTHERN GEORGIA...AND COASTAL SOUTH CAROLINA... ...SUMMARY... Severe thunderstorms will be possible over portions of southern Georgia into northern Florida Thursday morning, and through the afternoon across parts of the Florida Peninsula. A few tornadoes and scattered damaging winds should be the main threats. ...Florida into Southern Georgia and the Carolinas... A large-scale upper cyclone encompassing much of the central and eastern CONUS will remain centered over the Upper Midwest and Great Lakes on Thursday. A lead mid-level perturbation is forecast to quickly shift eastward over the East Coast states/Mid-Atlantic through the day. While the primary surface low will remain over the Upper Midwest, a secondary low over GA/SC Thursday morning should develop quickly northeastward across the Carolinas and coastal southeastern VA by Thursday evening. A related cold front will sweep eastward across FL, GA, and the Carolinas through the day. A broken line of thunderstorms will likely be ongoing at the start of the period across parts of north FL into GA along or just ahead of the cold front. Mid to upper 60s surface dewpoints should be in place ahead of this activity, and modest daytime heating should support weak instability across the FL Peninsula into coastal GA and SC. Even though the enhanced low-level flow will gradually veer and weaken through the day, it should still be sufficiently strong to support updraft rotation and a threat for a few tornadoes as convection spreads eastward through the early afternoon. Scattered damaging winds may also occur before thunderstorms eventually weaken Thursday evening. Farther north, a warm front is forecast to lift northward across central/eastern NC through the day, but meager daytime heating and related instability should keep the overall severe threat rather isolated across this area. Better prospects for surface-based convection will probably remain just offshore the Outer Banks of NC. ..Gleason.. 12/14/2022 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1025 AM CST Wed Dec 14 2022 Valid 141630Z - 151200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING OVER PORTIONS OF SOUTHEAST LOUISIANA...SOUTHERN MISSISSIPPI...AND WESTERN/SOUTHERN ALABAMA... ...SUMMARY... Tornadoes (some strong) and damaging thunderstorm gusts are expected today and tonight across southern parts of Louisiana, Mississippi and Alabama, and portions of the Florida Panhandle. ...Active severe weather event is anticipated this afternoon and evening for portions of the central Gulf Coast states... ...LA/MS/AL... Morning water vapor imagery shows an intense and progressive shortwave trough rotating across OK/TX. This feature is expected to become negatively tilted this evening over AR, with strong large-scale forcing overspreading much of the mid/lower MS Valley. Strong southerly low-level winds have established a very moist and potentially unstable air mass over parts of LA/MS/AL, with dewpoints in the 70s and visible satellite showing considerable breaks in the low clouds. This should result in ample CAPE by mid-afternoon. A consensus of 12z CAM guidance indicates that discrete supercell development will commence this afternoon over southeast LA into southern MS. This activity will likely persist through the evening and track into western and southern AL. Forecast soundings show very strong low-level vertical shear and favorable deep-layer shear for tornadoes, along with sufficient CAPE for robust thunderstorms. Low-level winds are expected to strengthen further during the afternoon with the approach of the upper trough. Tornadoes, including the possibility of strong and long-track tornadoes, are the primary concern today. Given the consistent signal in 12z guidance for numerous supercells, the favorable CAPE/shear environment, and the impressive nature of the shortwave trough, have opted to upgrade to MDT risk for portions of the area. ..Hart/Bentley.. 12/14/2022 Read more

No changes to the ongoing forecast. ..Wendt.. 12/14/2022 .PREV DISCUSSION... /ISSUED 0150 AM CST Wed Dec 14 2022/ ...Synopsis... As a deep upper-level cyclone slowly fills over the northern Plains, cool temperatures and higher humidity are expected across much of the southern and central High Plains. Lingering gusty northwest flow may occasionally reach 15-20 mph through the afternoon in the wake of a cold front moving east across the MS Valley. However, cooler temperatures and increasing moisture will limit diurnal RH minimums. In addition, recent precipitation has tempered area fuels such that large-fire spread is unlikely. Thus, fire-weather concerns are not expected. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 2015 CONCERNING TORNADO WATCH 582... FOR EAST/SOUTHEAST TX...NORTHWEST LA...SOUTHERN AR
Mesoscale Discussion 2015 NWS Storm Prediction Center Norman OK 0133 PM CST Tue Dec 13 2022 Areas affected...East/Southeast TX...Northwest LA...Southern AR Concerning...Tornado Watch 582... Valid 131933Z - 132130Z The severe weather threat for Tornado Watch 582 continues. SUMMARY...Threat for supercells capable of all severe hazards continues across Tornado Watch 582. A downstream Tornado Watch will likely be needed across southern AR, northwest LA, and east/southeast TX. DISCUSSION...Recent surface analysis places a triple point low about 20 miles east of PRX, with a cold front extending southwestward from this low through central TX. A warm front also extends southeastward from this low through northwest and central LA (delineated well by the 65 deg F isodrosotherm). Thunderstorm activity along the cold front has weakened over the last hour or so, while showers have increased throughout the warm sector. Most of these warm sector showers have not strengthened significantly. However, very recent trends have signaled some strengthening with the storms in Anderson, Houston, and Robertson Counties, evidenced by increasing reflectivity and lightning activity. Given their placement in the warm sector, some additional strengthen/maturing into supercells is possible. The warm front is expected to continue slowly lifting northward while the cold front advances eastward. This will take the warm sector farther east into more of east/southeast TX, northwest LA, and southern AR through this evening. As such an additional Tornado Watch will be needed for portions of the region within the next hour or so.
