SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0252 PM CST Wed Jan 28 2026 Valid 301200Z - 051200Z A series of mid-level shortwave troughs will cross the northern Plains toward the southeast Atlantic Coastline through the middle of next week as they traverse a broader northwesterly upper flow regime. As a result, a series of surface high pressure surges will reinforce a near to sub-freezing airmass over much of the CONUS, particularly from the Mississippi River and points east, limiting wildfire spread concerns over most locales. Dry and occasionally breezy conditions may develop on occasion over portions of the Florida Peninsula and central/southern High Plains. However, the anticipated conditions would likely only support localized wildfire spread, precluding Critical probabilities this outlook. ..Squitieri.. 01/28/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1221 PM CST Wed Jan 28 2026 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track. Dry northerly surface winds will persist across the Florida Peninsula. While such conditions favor localized wildfire-spread potential, wind speeds should be too weak for widespread, significant fire weather conditions, so fire weather highlights are not currently needed. ..Squitieri.. 01/28/2026 .PREV DISCUSSION... /ISSUED 0140 AM CST Wed Jan 28 2026/ ...Synopsis... A shortwave trough will move across the central Rockies on D2/Thursday, with a surface low developing across eastern Colorado. A mostly dry cold front will shift southward across the Southern Plains. Some period of increasing surface wind (first from the south becoming west and northwest as the front passes) will be possible. Temperatures will remain cool, with another reinforcing shot of cold arctic air behind the front. The continued cool conditions in addition to snow pack and generally wet fuels should keep fire concerns low. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1219 PM CST Wed Jan 28 2026 Valid 301200Z - 311200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm probabilities across the U.S. for Friday through Friday night appear less than 10 percent. ...Discussion... Models indicate that large-scale mid-level ridging will generally be maintained across the U.S. Pacific coast through Rockies, with short wave ridging also building along the British Columbia coast, in the wake of a short wave trough progressing inland across the Canadian and adjacent northern U.S. Rockies. Precipitation accompanying an associated baroclinic zone may linger into Friday across the Pacific Northwest, with perhaps an upstream warm frontal band also approaching coastal Washington by late Friday night. However, forecast soundings suggest that thermodynamic profiles will not become sufficiently unstable to support an appreciable risk for thunderstorm activity. Downstream, several short wave perturbations, including one vigorous impulse emerging from the Hudson Bay vicinity, are forecast to consolidate into amplifying, positively tilted large-scale troughing across much of the lower Mississippi Valley and Gulf Basin through southern Atlantic Seaboard by late Friday night. There remains notable spread concerning associated surface cyclogenesis, but it appears that this will remain weak across the eastern Gulf and adjacent Southeast, before undergoing notable strengthening offshore of the southern/mid Atlantic coast after 12Z Saturday. Along and south of a strengthening frontal zone, a deepening moist boundary-layer may become conditionally unstable across parts of the Florida Keys and southeastern Florida Peninsula by Friday. However, forecast soundings indicate that relatively warm and dry air in mid/upper levels will tend to suppress thunderstorm development. ..Kerr.. 01/28/2026 Read more

Fire weather concerns are expected to remain low today across the CONUS. A cool and dry air mass will remain in place, with extensive snow pack reaching from the Southern Plains into portions of the Northeast. Overall, the recent cold and wet pattern has improved status of fuels in many areas. Some dry conditions will continue across southern Florida but mostly light winds will preclude the need to include any areas. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1008 AM CST Wed Jan 28 2026 Valid 291200Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm probabilities across the U.S. appear less than 10 percent for Thursday through Thursday night. ...Discussion... Models indicate that mid/upper ridging will build inland of the Pacific coast, across the Sierra Nevada through the Canadian Rockies and western Prairies, through this period. As this occurs, a series of short wave perturbations emerging from evolving large-scale upstream troughing are forecast to approach the British Columbia/Pacific Northwest, within deep-layer southwesterly flow. Continuing low/mid-level moisture return is likely to support another round of precipitation with an inland migrating baroclinic wave. However, beneath relatively warm mid/upper levels, saturating thermodynamic profiles appear unlikely to become supportive of thunderstorm development. Meanwhile, an inland migrating short wave trough, preceding the building ridge, is forecast to dig across the Great Basin and Rockies, through the south central Great Plains and lower Mississippi Valley by late Thursday night, as a much more prominent short wave trough pivoting southwest of Hudson Bay progresses across the international border into the Upper Midwest. Beneath a confluent regime in the wake of the latter perturbation, it appears that another cold surface ridge will begin building across the international border through the northern Great Plains and upper Mississippi Valley. In advance of the perturbation emerging from the West, a weak developing lee surface low may be maintained across the Red River and lower Mississippi Valleys, while perhaps another weak wave develops along a remnant preceding frontal zone across the northwestern Gulf Basin. However, models indicate that western Gulf boundary-layer modification and inland moisture return will be quite limited, with little potential for destabilization supportive of an appreciable risk for thunderstorm activity. ..Kerr.. 01/28/2026 Read more

Thunderstorms are not forecast for today. ...Synopsis... Early-morning satellite imagery shows a pair of shortwave troughs within in the cyclonic flow covering the central and eastern CONUS. The southernmost shortwave is currently progressing southeastward into the Lower MS Valley, with this southeastward motion expected to persist throughout the day. This evolution takes the wave across the north-central and eastern Gulf this afternoon/evening, and across FL by early tomorrow morning. The northern shortwave is moving southeastward over the Upper Great Lakes, and continued southeastward progress will take this wave through the middle/upper OH Valley and off the northern Mid-Atlantic coast tonight. Dry and stable conditions associated with an arctic airmass will be in place ahead of these shortwaves, limiting low-level moisture and precluding thunderstorm development. Another shortwave trough is currently moving eastward across the interior Pacific Northwest and northern Great Basin. This eastward/southeastward progression should continue, taking the wave through the northern/central Rockies and into the central Plains while also dampening the shortwave ridging proceeding it. Precipitation will be possible in association with this shortwave during the day and across the central and northern Rockies. However, little to no instability is forecast, and thunderstorms appear unlikely. ..Mosier/Broyles.. 01/28/2026 Read more

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0356 AM CST Wed Jan 28 2026 Valid 311200Z - 051200Z ...DISCUSSION... Severe weather is unlikely through the extended forecast period. A highly amplified mid-level flow pattern over the CONUS will continue through this weekend and into the first part of next week. A prominent upper low will amplify over the East Coast as a strong surface cyclone develops offshore. Ridging over the western US will support strong high pressure and a cold/dry continental air mass over much of the US. This will largely suppress inland moisture transport, outside of far south FL, and subsequent thunderstorm potential for the next several days. Read more
