Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0252 PM CDT Tue Mar 26 2024 Valid 262000Z - 271200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF LOWER MICHIGAN...EASTERN INDIANA...AND WESTERN OHIO... ...SUMMARY... Damaging wind gusts remain possible late this afternoon into the evening over parts of the Lower Michigan/southern Great Lakes region, and the eastern Gulf Coastal Plain. ...20Z Update... Severe probabilities have been trimmed across parts of IN and southwest lower MI, in the wake of a cold frontal passage. Otherwise, no changes have been made. See the previous discussion below and MCD 307 for more details. A small part of the Marginal Risk has been trimmed across the FL Panhandle, based on the progression of ongoing convection. See the previous discussion below for more details regarding the threat across the FL Peninsula and south GA. ..Dean.. 03/26/2024 .PREV DISCUSSION... /ISSUED 1101 AM CDT Tue Mar 26 2024/ ...FL Panhandle and Vicinity... A surface cold front continues to sag southward across parts of AL and the FL Panhandle. Scattered thunderstorms are occurring along the front (mainly offshore), with occasional updrafts showing some organization. It is expected that the bulk of this activity will remain offshore due to widespread clouds and limited destabilization inland. However, there is some chance of a strong storm or two this afternoon. After dark, most model guidance suggest the frontal convection will strengthen, with a continued risk of a few strong storms into north FL. ...Lower MI/IN/Western OH... A strong cold front is sweeping eastward into western IN late this morning, and will move across Lower MI/IN/western OH through the day. Widespread clouds and meager low-level moisture ahead of the front will limit destabilization, with forecast soundings suggesting the convective layer may remain too shallow to support much lightning. Nevertheless, strong winds just above the surface coupled with cold temperatures aloft may be sufficient for a few strong storms later today, capable of damaging wind gusts. The time period of greatest concern should roughly be from 22-02z. Read more

MD 0307 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR MUCH OF LOWER MICHIGAN...NORTHEASTERN INDIANA...NORTHWESTERN OHIO
Mesoscale Discussion 0307 NWS Storm Prediction Center Norman OK 0108 PM CDT Tue Mar 26 2024 Areas affected...much of lower Michigan...northeastern Indiana...northwestern Ohio Concerning...Severe potential...Watch unlikely Valid 261808Z - 262045Z Probability of Watch Issuance...20 percent SUMMARY...An increasingly organized band of showers, and developing thunderstorms, may be accompanied by increasing potential for strong to locally severe surface gusts by 4-5 PM EDT. It is still not clear that a severe weather watch is needed, but trends are being monitored for this possibility. DISCUSSION...Weak destabilization within a narrow pre-frontal corridor of low-level warming and moistening, coupled with large-scale ascent aided by warm advection, has contributed to increasing showers across western lower Michigan southward toward the Indianapolis IN vicinity. Some lightning has recently been noted southeast of South Bend, but low-level lapse rates are still relatively modest and the moistening is only contributing to very weak CAPE. This may be slow to improve, but breaks in cloud cover may allow for at least some continuing insolation during the next few hours. Perhaps more notably, within the left exit region of an intensifying mid-level jet (in excess of 100 kt around 500 mb) nosing north-northeastward through the lower Ohio Valley, strengthening low-level frontogenetic forcing is forecast along the eastward advancing front across central lower Michigan through the Indiana/Ohio border area by 20-21Z. This may support a consolidating and deepening band of convection with increasing potential to produce lightning. In the presence of fairly strong (and strongly sheared) south-southwesterly lower/mid-tropospheric flow (including 40-50+ kt mean ambient flow in the lowest 3-6 km AGL), activity may become increasingly organized. Downward mixing of momentum may contribute to potentially damaging wind gusts reaching the surface in northeastward surging segments, while the line advances eastward toward the lower Great Lakes region through late afternoon. ..Kerr/Hart.. 03/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0306 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL FLORIDA PANHANDLE
Mesoscale Discussion 0306 NWS Storm Prediction Center Norman OK 1204 PM CDT Tue Mar 26 2024 Areas affected...central Florida Panhandle Concerning...Severe potential...Watch unlikely Valid 261704Z - 261900Z Probability of Watch Issuance...5 percent SUMMARY...Marginal risk of wind and a tornado through the afternoon. DISCUSSION...A broken line of convection is ongoing this afternoon across southern Alabama into the central Florida Panhandle. This activity remains elevated, with surface inhibition evident from modified 12z observed soundings from Tallahassee and in forecast RAP soundings along the Gulf. In addition, extensive mid-level cloud cover remains in place across much of the Panhandle this afternoon, limiting destabilization. As a result, the most favorable warm sector remains offshore, with minimal MLCAPE observed inland. Over the next couple of hours as this convection moves eastward, a few instances of more robust embedded storms may be possible where the warm sector can creep inland. Wind profiles indicate deep layer shear around 55-60 kts. Given that convection is likely rooted above the surface, much of the low-level cyclonic curvature of hodographs will not be realized. Should the warm sector move inland and a storm could become surface based, an isolated tornado could be possible, though weak low-level lapse rates and strong surface inhibition will likely work to further inhibit this potential. Otherwise, the main threats will remain occasional gusty winds. A watch is unlikely to be needed at this time. ..Thornton/Hart.. 03/26/2024 ...Please see www.spc.noaa.gov for graphic product...

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1229 PM CDT Tue Mar 26 2024 Valid 271200Z - 281200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS NORTH FLORIDA AND ALSO ACROSS PARTS OF NORTH-CENTRAL TEXAS... ...SUMMARY... Isolated strong to severe thunderstorms may occur Wednesday across north Florida, and also across parts of north-central Texas. Isolated hail and damaging winds should be the main hazards for both areas. ...Florida into the Carolinas... A cold front is forecast to gradually move eastward across parts of Florida into the Carolinas on Wednesday, in conjunction with the southern portion of a deep upper-level trough moving into the eastern CONUS. Early-day convection and related cloudiness may tend to limit destabilization, but some diurnal heating along the eastern periphery of the morning convection may support MLCAPE increasing above 1000 J/kg by early afternoon. Favorable deep-layer shear will support potential for a few strong storms through the forecast period, with potential for isolated hail and damaging gusts. Multiple rounds of storms will be possible in some areas, with some convection lingering through the morning, and later redevelopment possible in areas where stronger heating occurs, and also potentially along the trailing cold front. Farther north, a strong storm or two cannot be ruled out from southeast GA into the coastal Carolinas vicinity, along/ahead of the cold front. However, there is greater uncertainty regarding potential for destabilization across these areas in the wake of morning convection. If some diurnal heating/destabilization can occur in advance of the front, then an isolated severe threat could eventually evolve, though uncertainty remains too high to include severe probabilities at this time. ...Parts of north into central TX... Despite generally meager low-level moisture across the region, cold temperatures aloft (500 mb temperatures around -25C) will support modest diurnal destabilization from north into central TX. Isolated to widely scattered thunderstorm development is expected by late afternoon. Deep-layer shear will be sufficient for some storm organization, and a southeastward-moving supercell or two will be possible. Hail may be the most likely hazard, given the cold temperature profiles, but steep lapse rates could also support isolated strong/damaging gusts. ..Dean.. 03/26/2024 Read more

Isolated strong to severe thunderstorms may occur Wednesday across north Florida, and also across parts of north-central Texas. Isolated hail and damaging winds should be the main hazards for both areas. ...Florida into the Carolinas... A cold front is forecast to gradually move eastward across parts of Florida into the Carolinas on Wednesday, in conjunction with the southern portion of a deep upper-level trough moving into the eastern CONUS. Early-day convection and related cloudiness may tend to limit destabilization, but some diurnal heating along the eastern periphery of the morning convection may support MLCAPE increasing above 1000 J/kg by early afternoon. Favorable deep-layer shear will support potential for a few strong storms through the forecast period, with potential for isolated hail and damaging gusts. Multiple rounds of storms will be possible in some areas, with some convection lingering through the morning, and later redevelopment possible in areas where stronger heating occurs, and also potentially along the trailing cold front. Farther north, a strong storm or two cannot be ruled out from southeast GA into the coastal Carolinas vicinity, along/ahead of the cold front. However, there is greater uncertainty regarding potential for destabilization across these areas in the wake of morning convection. If some diurnal heating/destabilization can occur in advance of the front, then an isolated severe threat could eventually evolve, though uncertainty remains too high to include severe probabilities at this time. ...Parts of north into central TX... Despite generally meager low-level moisture across the region, cold temperatures aloft (500 mb temperatures around -25C) will support modest diurnal destabilization from north into central TX. Isolated to widely scattered thunderstorm development is expected by late afternoon. Deep-layer shear will be sufficient for some storm organization, and a southeastward-moving supercell or two will be possible. Hail may be the most likely hazard, given the cold temperature profiles, but steep lapse rates could also support isolated strong/damaging gusts. ..Dean.. 03/26/2024 Read more
