Upper ridging will persist from the Plains states eastward to the Atlantic coastline as a mid-level trough meanders off of the coast of California tomorrow/Wednesday. Surface high pressure and cooler air will continue to dominate west of the Rockies and east of the Mississippi River, as on Day 1. Low-level moisture return across the Plains states, driven by surface lee troughing, will also dampen significant wildfire-spread potential as well. ..Squitieri.. 12/19/2023 ..…

SPC Day 1 Fire Weather Outlook Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1216 AM CST Tue Dec 19 2023 Valid 191200Z - 201200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough will eject into the Atlantic as a second mid-level trough impinges on the West Coast and upper ridging dominates the central CONUS today. Surface high pressure and associated cooler air will overspread much of the U.S. west of the Rockies and east of the Mississippi River, promoting quiescent fire weather conditions. Likewise, weaker surface winds or higher RH amid poorly receptive fuels should limit significant wildfire-spread potential across the Plai…

A few thunderstorms are possible across northern California. ...California... An area of modest midlevel height falls will spread south along the CA Coast and adjacent offshore areas as an upper low digs to near 36N/127W by the end of the period. While the primary surface front should not advance inland, weak boundary-layer heating should contribute to weak surface-based buoyancy across portions of northern CA within favorable high-level diffluent flow aloft. Fore…

Thunderstorm potential is low tonight. ...01z Update... Midlevel speed max is translating inland across northern CA this evening. Associated short-wave trough will deamplify as it ejects into OR later tonight. Very little/no lightning has been observed with weak convection ahead of this feature. 00z sounding from OAK exhibits poor lapse rates with meager buoyancy. While some large-scale forcing for ascent will be noted early this evening, meaningful destabilization is no…

Transient ridging will slowly build over the central US, keeping winds light and temperatures cool to mild. A deep trough will persist off the Atlantic Coast through the next several days before it slowly departs to the east. At the same time, a cut off low and shortwave trough over the eastern Pacific will support continuous onshore flow of moisture across parts of …
