SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1100 AM CST Fri Nov 10 2023 Valid 111200Z - 121200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few lightning flashes will be possible across portions of northern Washington state, and near the central Gulf Coast area. ...Discussion... Fast, low-amplitude flow aloft will persist across the U.S. Saturday, with multiple embedded/weak disturbances traversing the country through the period. At the surface, high pressure will largely prevail over the eastern half of the country, north of a weak Gulf Coastal baroclinic zone, and a High-Plains lee trough that will migrate eastward into the lower Plains with time. Thunderstorm activity will remain subdued across the country. A few flashes may occur over portions of northern Washington State and vicinity as a short-wave trough moves inland across western Canada. A few flashes may also occur near, and just off, the central Gulf Coast near the weak surface boundary. Elsewhere, a flash or two cannot be ruled out over portions of the central Plains in conjunction with a weak/fast-moving trough, and near the Texas Gulf Coast early in the period. ..Goss.. 11/10/2023 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0944 AM CST Fri Nov 10 2023 Valid 101700Z - 111200Z ...NO CRITICAL AREAS... The current D1 Fire Weather Outlook remains on track with no updates needed. See previous discussion below. ..Thornton.. 11/10/2023 .PREV DISCUSSION... /ISSUED 0101 AM CST Fri Nov 10 2023/ ...Synopsis... Fire weather concerns are expected to remain limited for today. Weak lee troughing across the High Plains may support areas of dry and breezy conditions, but the potential for meteorological conditions maintaining elevated wind/RH thresholds appears low. Offshore flow may persist during the morning and early afternoon hours across the southern CA coast, but elevated wind/RH conditions are expected to remain fairly localized to the higher, typically wind-prone, terrain. ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0924 AM CST Fri Nov 10 2023 Valid 101630Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated lightning flashes will be possible along parts of the Gulf coast, far west Texas/southern New Mexico, and the Olympic Peninsula of Washington. ...Synopsis... Mainly zonal flow aloft will overspread the CONUS, with mid-level troughs overspreading the Southwest and impinging on the Pacific Northwest through today. Surface high pressure and associated cooler air will reinforce static stability across most of the CONUS, limiting thunderstorm potential. A few lightning flashes remain possible over southern NM/Far West TX for a few more hours, before mid-level trough de-amplification reduces the thunderstorm threat. Otherwise, a few flashes remains possible for the remainder of the Day 1 period over parts of the Gulf Coast, given weak moisture advection atop a southward-sagging cold front. Finally, a few lightning flashes may occur across far northwest WA with the approach of a mid-level trough. ..Squitieri.. 11/10/2023 Read more

Day 4-8 Outlook
Day 4-8 Convective Outlook RESENT 1 NWS Storm Prediction Center Norman OK 0847 AM CST Fri Nov 10 2023 Valid 131200Z - 181200Z ...DISCUSSION... ...Monday/Day 4 to Wednesday/Day 6... An upper-level trough is forecast to move from the middle Rio Grande Valley on Monday to the Lower Mississippi Valley on Tuesday, and to the eastern Gulf Coast states by Wednesday. A moist airmass is forecast to advect northward into the central Gulf Coast ahead of the approaching trough. Increasing low-level flow across the western Gulf of Mexico Monday will make conditions favorable for MCS development. The MCS will likely move eastward across the northern Gulf of Mexico on Tuesday. Surface dewpoints could reach the lower to mid 60s F across the central Gulf Coast just ahead of the trough during the day. The northern part of the MCS could first affect southeastern Louisiana on Tuesday, and then move across far southern Mississippi, far southern Alabama and the Florida Panhandle Tuesday night. Wednesday, thunderstorms may develop across parts of the Florida Peninsula. Although a severe weather threat can not be ruled out, the models have some variance concerning the quality of low-level moisture ahead of the system. If the more aggressive solutions pan out, then a marginal tornado threat would be possible on Tuesday across the central Gulf Coast. The current thinking is that the higher quality low-level moisture and more significant part of the MCS will remain offshore, keeping any severe threat over the water. ...Thursday/Day 7 and Friday/Day 8... An upper-level trough is forecast to develop across the central U.S. on Thursday, and move into the eastern U.S. on Friday. The shortwave trough in the Southeast is forecast to move eastward into the western Atlantic. In the wake of this system, instability is forecast to be limited across the Gulf Coast states and along the Atlantic Seaboard, minimizing any potential for thunderstorm development. Read more
