ACUS02 KWNS 250558 SWODY2 SPC AC 250556 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1256 AM CDT Tue Mar 25 2025 Valid 261200Z - 271200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE PACIFIC NORTHWEST... ...SUMMARY... Isolated severe thunderstorms are possible across parts of the Pacific Northwest on Wednesday afternoon into the evening. ...Synopsis... Slow progression of the upper pattern -- a general western ridge/eastern trough configuration -- is expected Wednesday. Upstream, an eastern Pacific trough/low will strengthen as it nears the Pacific Northwest Coast. At the surface, a rather ill-defined baroclinic zone will extend from Florida to Texas. Meanwhile, a cold front -- associated with a deepening/occluded low off the coast -- will shift into the Pacific Northwest through the day. ...Pacific Northwest... Ahead of the cold front forecast to move eastward across the area during the afternoon and evening, daytime heating of a modestly moist boundary layer will result in at least marginal destabilization. Questions persist regarding the degree of low-level moisture, which will likely modulate storm development and subsequent intensity. With that said, diffluent flow aloft ahead of the approaching upper low, and increasingly strong southerly deep-layer flow would otherwise suggest a favorable setup for isolated severe storms. At this time, will maintain 5%/MRGL risk for hail/wind, as low-level flow/shear should remain weak. However, the favorable overall setup could yield greater coverage/risk than currently indicated, and thus modifications in subsequent outlooks may be needed. ...Far West Texas vicinity... A dry/capped airmass and weak shear is expected across the Permian Basin/Transpecos Region/Davis Mountains. However, presuming an isolated storm or two can develop near the dryline, steep lapse rates aloft would suggest potential for briefly intense updrafts. Any storm which would develop could produce hail/wind, but any risk is highly conditional and does not appear to warrant inclusion of a risk area at this time. ..Goss.. 03/25/2025 $$ --- SBBSecho 3.20-Linux * Origin: capitolcityonline.net * Telnet/SSH:2022/HTTP (618:250/1) |
