Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 323 AM EDT Mon Sep 23 2013 Valid 12Z Mon Sep 23 2013 - 12Z Wed Sep 25 2013 ***Stormy weather for the Gulf Coast and Florida*** ***High quality airmass moving into the Eastern U.S.*** ***Active weather pattern over the Pacific Northwest*** The southern part of the cold front that progressed across the Eastern U.S. this past weekend is forecast to remain stalled near the Gulf Coast for the beginning of the work week. A wave of low pressure on this front over the northern Gulf will help to focus moisture near this front and result in numerous showers and storms from southern Louisiana to the Florida peninsula. Farther to the north from the Carolinas to New England, a fresh and high quality airmass is now in place and forecast to remain over the next couple of days. This surface ridge of high pressure will bring continued fall-like weather with highs in the 60s and 70s, and lows in the 40s and 50s, along with lower humidity. Onshore flow over the northern Pacific Coast is expected to continue through the forecast period, and this will aid in orographically driven rainfall for the Pacific Northwest. Some of this moisture should make it to the Northern Rockies, where scattered showers are likely. Showers are also expected for the Northern Plains as a frontal boundary moves through the region.
