SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1236 AM CDT Thu Mar 20 2025 Valid 201200Z - 211200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN HIGH PLAINS... ...CRITICAL FIRE WEATHER AREA FOR THE SOUTHEASTERN FLORIDA PENINSULA... ...Synopsis... Critical fire weather conditions are expected again today across parts of the southern High Plains, albeit more spatially confined than previous days, as well as across portions of the Florida Peninsula. A strong surface low and an attendant cold front are expected to translate east across the upper Great Lakes and Mid-Atlantic through the day. It its wake, surface ridge will build from the Gulf Coast into the Midwest with widespread dry conditions (15-35% RH) likely to the west of the ridge axis. ...High Plains... Across the Pacific Northwest, an approaching low-amplitude upper wave will begin impinging on the northern Rockies, resulting in modest lee troughing along the High Plains. The resultant west/southwesterly downslope flow regime should foster sustained winds between 15-25 mph. Confidence in sustained 20-25 mph winds remains highest across northeast NM and into southeast CO and adjacent parts of the OK/TX Panhandles, but such winds are also possible further south into southwest TX and further north across southeast WY into the NE Panhandle. Afternoon RH minimums in the teens to low 20s, coupled with antecedent dry fuels - especially across NM and TX where precipitation has been minimal - should support the fire weather concern. Fire weather concerns are possible across parts of east-central CO where dry/downslope conditions are expected, but recent snowfall should limit fuel status. ...Florida... Dry conditions are expected to persist across much of central and southern FL ahead of the frontal passage later in the afternoon. Pre-frontal westerly winds are forecast to increase to near 15 mph with gusts up to 20 mph possible. Forecast high temperatures are expected to approach the 90th percentile for south FL in mid-March, which when coupled with mid-50s dewpoints, should result in RH values between 20-35% by peak heating. Despite some rainfall over the past 48 hours, recent fire activity indicates that fuels will support fire spread. Critical fire weather conditions appear most likely along the southeastern FL coast where conditions are expected to be warmest/driest, but may spread further inland and northward into central FL prior to the late-afternoon frontal passage. ...Louisiana Coast and lower MS River Valley... Northwesterly winds near 15 mph are expected through the morning and early afternoon hours in the immediate wake of the cold front across the lower MS River Valley and central Gulf coast. Winds are expected to diminish through peak heating as the surface ridge builds in from the west. Consequently, the temporal overlap of breezy winds and RH minimums is expected to be limited, though areas of elevated fire weather conditions are possible for a couple of hours from the LA coast northeastward along the MS River, including eastern AR where notable fire activity was observed yesterday outside of the heavy rain swaths that occurred during the 3/14 to 3/15 period. ..Moore.. 03/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1146 PM CDT Wed Mar 19 2025 Valid 201200Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm development will be possible today in parts of the Mid-Atlantic and northern Rockies. Severe weather is not expected. ...Synopsis and Discussion... A strong upper trough will move rapidly across the eastern states today, with primary midlevel speed max sweeping across the Gulf Coast states and nosing into the Carolinas during the afternoon. Cooling aloft with this system will be substantial as a band of strong meridional flow approaches the East Coast late in the day. At the surface, a trough will deepen slightly ahead of a cold front with strongest afternoon push from GA into the Carolinas where 850 mb winds will exceed 40 kt out of the west/southwest. While an elongated north-south band of precipitation is likely to accompany the cold front, instability is forecast to be quite weak. MUCAPE of 100-200 J/kg may develop near the front, perhaps effectively elevated as the front undercuts meager moisture return and lapse rates steepen aloft. A plume of steeper low-level lapse rates will accompany the dry slot from GA into the Carolinas, but forecast soundings indicate little severe potential due to limited moisture. As such, severe storms are not forecast, but locally gusty winds are expected with the band of showers and due to vertical mixing considerations. ..Jewell/Moore.. 03/20/2025 Read more

MD 0252 CONCERNING SEVERE THUNDERSTORM WATCH 59... FOR SOUTHEASTERN INDIANA...SOUTHWESTERN OHIO...AND A SMALL PORTION OF NORTHERN KENTUCKY
Mesoscale Discussion 0252 NWS Storm Prediction Center Norman OK 1004 PM CDT Wed Mar 19 2025 Areas affected...southeastern Indiana...southwestern Ohio...and a small portion of northern Kentucky Concerning...Severe Thunderstorm Watch 59... Valid 200304Z - 200430Z The severe weather threat for Severe Thunderstorm Watch 59 continues. SUMMARY...Severe risk continues to gradually diminish across the WW area. DISCUSSION...Radar data continues to show a gradual decrease in convective intensity with storms moving across Indiana/WW 69 over the past couple of hours. This coincides with an associated, gradual decrease in buoyancy, with RAP-based objective analysis now showing mixed-layer CAPE below 500 J/kg across the WW area, and even less with eastward extent toward central Ohio. Expectations continue to be that storms will continue to gradually weaken, and thus risk for severe-caliber gusts waning. While local WW extension in area may be considered for a couple of counties in western Ohio, overall risk should remain minimal for the remainder of the evening. ..Goss.. 03/20/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0251 CONCERNING TORNADO WATCH 58... FOR WEST-CENTRAL KENTUCKY INTO MIDDLE TENNESSEE
Mesoscale Discussion 0251 NWS Storm Prediction Center Norman OK 0756 PM CDT Wed Mar 19 2025 Areas affected...West-central Kentucky into middle Tennessee Concerning...Tornado Watch 58... Valid 200056Z - 200300Z The severe weather threat for Tornado Watch 58 continues. SUMMARY...The tornado and damaging wind threat for the next few hours will likely be focused across parts of central to western Kentucky and into northern middle Tennessee. DISCUSSION...Thunderstorms continue to develop southward along and just ahead of the dryline across western KY into western TN. Weak storm motions off the boundary are favoring slow upscale growth into semi-discrete cells and clusters, but several shallow, but intensifying, discrete cells have recently developed across middle TN ahead of the developing line. The deeper/more intense cells are showing signs of organized mid-level mesocyclones, suggesting that they are beginning to realize the strongly sheared environment. Recent VWP observations from KOHX show 1-2 km winds increasing to 60-70 knots as the low-level jet strengthens. Middle TN is likely on the southern periphery of the developing low-level jet, but as storms move north into the stronger low-level flow/higher SRH environment they may continue to organize and pose a more robust tornado/damaging wind threat in the coming hours across parts of west-central KY and northern middle TN. To the west, the continued organization of the squall line may favor and increasing damaging wind threat downstream. It remains unclear quickly onset of nocturnal cooling and slowly diminishing buoyancy will offset this potential. ..Moore.. 03/20/2025 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 58 NWS Storm Prediction Center Norman OK 315 PM CDT Wed Mar 19 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southern Illinois Southern Indiana Western and Central Kentucky * Effective this Wednesday afternoon and evening from 315 PM until 1100 PM CDT. * Primary threats include... A few tornadoes possible Scattered damaging wind gusts to 70 mph possible Scattered large hail events to 1.5 inches in diameter possible SUMMARY...A band of severe thunderstorms is expected to move eastward across the watch area from late afternoon into this evening. These storms may produce a few tornadoes, scattered wind damage, and hail. The tornado watch area is approximately along and 70 statute miles north and south of a line from 70 miles west southwest of Evansville IN to 20 miles south of Louisville KY.

MD 0250 CONCERNING SEVERE THUNDERSTORM WATCH 59... FOR INDIANA AND SOUTHERN LOWER MICHIGAN
Mesoscale Discussion 0250 NWS Storm Prediction Center Norman OK 0748 PM CDT Wed Mar 19 2025 Areas affected...Indiana and southern Lower Michigan Concerning...Severe Thunderstorm Watch 59... Valid 200048Z - 200215Z The severe weather threat for Severe Thunderstorm Watch 59 continues. SUMMARY...Local risk for damaging wind gusts continues. DISCUSSION...Latest radar loop shows a broken -- and gradually weakening -- band of pre-frontal storms moving eastward across central and northern Indiana. While more vigorous cells within this band persist farther south -- into portions of Tornado Watch 58 where slightly greater surface dewpoints (low to mid 50s) exist, the prior, limited tornado risk over central and northern Indiana has further diminished. While a brief spin-up is still possible, the predominant severe risk will remain locally damaging wind gusts. In the wake of the initial band, a second band of frontal convection near the Illinois/Indiana border will reach western fringes of WW 59 over the next hour or so -- which may bring an additional chance for wind gusts in excess of severe levels locally. Overall though, a gradual/nocturnal decrease in storm intensity within both of the aforementioned bands will continue over the next few hours. ..Goss.. 03/20/2025 ...Please see www.spc.noaa.gov for graphic product...
