SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1122 PM CDT Sun Mar 12 2017 Valid 151200Z - 161200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the USA on Wednesday. ...Synopsis... With a large area of cyclonic flow aloft enveloping the northeast, a surface high will settle into the OH/TN valleys, providing stable air across most of the central and eastern states. The exception will be across central and southern TX, where southerly surface winds around the high will begin to bring 50s to near 60 dewpoints into the region. Despite some moistening, the air mass is expected to remain capped, and with little to favor lift except weak warm advection. To the west, an upper trough will move across the Pacific northwest with strong cooling aloft and widespread showers likely. However, any instability will be very weak, and storms are unlikely. ..Jewell.. 03/13/2017
