SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1141 PM CST Tue Nov 19 2024 Valid 201200Z - 211200Z ...Synopsis... An upper-level low initially in the northern Plains will shift eastward into the Upper Midwest and intensify today. Strong low to mid-level winds will continue across portions of the central Plains as an associated surface low deepens in the Lower Great Lakes region. ...Central Plains... Temperatures will again be rather cool (mid/upper 40s F appear most probable). However, strong surface winds of 15-25 mph (with higher gusts) are likely across parts of eastern Wyoming into adjacent South Dakota and western Nebraska. RH will also fall to near 20% given the very dry airmass. Some fire weather concern could develop in fine fuels. Some weakening of the pressure gradient is expected by late afternoon which will limit the duration of the threat. ..Wendt.. 11/20/2024 ...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 1058 PM CST Tue Nov 19 2024 Valid 201200Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe weather is not expected Today. ...Discussion... An upper low initially over the north-central U.S. is forecast to shift southeastward across the Upper Great Lakes region with time, deepening through the second half of the period. Meanwhile, a second low is forecast to remain off the Pacific Northwest Coast. At the surface, an occluded low will shift across the Upper Great Lakes in tandem with the upper cyclone, while a cold front crosses the Appalachians through the first half of the period. Overnight, the front will move off the Middle and Southern Atlantic Coast, lingering only across southern portions of Florida by the end of the period Thursday morning. With a zone of strong onshore/upslope southwesterly flow across the Pacific Northwest southeast of the offshore upper low, showers and occasional lightning flashes will occur, with lightning potential focused near the Coast Ranges. Showers and embedded thunderstorms will also be possible across the Mid-Atlantic states south to North Carolina, ahead of the advancing surface cold front. Given weak/slightly elevated instability anticipated across this area, severe weather is not expected. Finally, showers and a few thunderstorms are forecast across portions of the Florida Peninsula, but with weak lapse rates and modest flow aloft, severe storms are not anticipated. ..Goss/Wendt.. 11/20/2024 Read more

Severe thunderstorm potential is expected to remain minimal through tonight. ...Discussion... An area of showers and thunderstorms is currently moving out of the central/into the eastern Gulf of Mexico, will all lightning currently relegated to offshore areas. Still, a few flashes will be possible overnight -- perhaps as far inland as the southern Appalachians. As the Gulf convection moves eastward, a stronger storm or two may affect the Florida Big Bend area, with gusty winds or even a waterspout near the coast not entirely out of the question. However, any severe potential appears far too low to warrant an areal outline. Otherwise, a few lightning flashes may move onshore across the Pacific Northwest later tonight, within a convective band moving eastward ahead of the strong/offshore upper low. Severe-weather potential appears negligible. ..Goss.. 11/20/2024 Read more
