Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0150 PM CST Wed Nov 20 2024 Valid 202000Z - 211200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms appear unlikely through tonight across the contiguous United States. ...20z Update... No changes are needed to the current D1 Convective Outlook. See previous discussion below for more information. ..Thornton/Smith.. 11/20/2024 .PREV DISCUSSION... /ISSUED 1030 AM CST Wed Nov 20 2024/ ...Mid-Atlantic into North Carolina... Midday water-vapor imagery shows a cyclone over the Upper Midwest that will move eastward across the Great Lakes through tonight. A cold front will advance eastward over these regions. While low-level moisture will gradually increase across NC into the southern Mid-Atlantic by early evening, considerable cloud cover and relatively meager lapse rates will only result in pockets of weak instability. Nonetheless, low-topped convection should still form along or just ahead of the cold front across eastern OH into western PA and WV by late this afternoon according to the latest guidance. This elevated convection is forecast to continue moving eastward over the southern Mid-Atlantic this evening and overnight. However, boundary-layer instability is forecast to remain minimal with eastward extent, which should limit the storm intensity. ...Coastal Pacific Northwest... A powerful upper cyclone west of British Columbia will occlude and gradually move away from the coast. Low-level warm advection will support intermittent low-topped convection across coastal portions of the Pacific Northwest. With surface dewpoints generally in the low to mid 40s over land, instability will remain scant---precluding a severe risk. Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0106 PM CST Wed Nov 20 2024 Valid 221200Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated to scattered thunderstorms are possible along the Pacific Northwest Coast on Friday. ...Synopsis... A large upper low will start to move off the East Coast on Friday. In its wake, a dry/cool continental airmass will overspread the eastern CONUS which will result in no thunderstorm threat. ...Pacific Northwest Coast... Cooling air aloft across the northeast Pacific, associated with the approaching mid-level trough, will lead to enough instability over the water to support some thunderstorm activity. Some of these thunderstorms may impact coastal areas during the day on Friday. Very strong synoptic winds are likely along the coast as a sub-990mb low moves north along the coast. Thunderstorm activity could enhance some of these winds and lead to increased wind damage threat, but instability is too limited for a marginal risk at this time. ..Bentley.. 11/20/2024 Read more

The previous forecast remains on track with no changes needed. Portions of central to northern FL saw only light rainfall over the past 24 hours, per MRMS rainfall estimates.

For Thursday, a strong upper low over the Upper Midwest will shift into the Mid-Atlantic by Friday morning. The post-frontal airmass behind the cold front in the Southeast/Florida will lead to RH reductions by the afternoon across these areas. Generally light winds and preceding precipitation should limit most fire weather concerns. Depending on the amount of precipitation that falls on late Tuesday into early Wednesday, a modest increase in fire weather concerns could occur in parts of northern/central Florida which have seen little rainfall in the last week.
