SYNOPSIS AND OUTLOOK
A complicated weather pattern with deep Gulf moisture moving north, a couple of weak cold fronts/dry lines slowly pushing into Texas and an upper-level low pressure trough will combine to keep a good chance of showers or thunderstorms in our picture through the weekend.
This morning, a slow-moving cold front extends north from Mexico to a low in eastern New Mexico. A second frontal boundary extends east from that low across the Texas Panhandle, the Red River area and Deep South to lows in North Carolina and the Atlantic. Elsewhere, a cold front is pushing into Washington, Oregon and Northern California with a low over Canada.
At the upper-levels, we are in a split flow with a broad, weak high pressure ridge over the eastern half of the country and upper-level lows over western Montana and over Utah and Arizona with an associated trough digging south into Baja California and the Pacific.
Partly to mostly cloudy skies and periods of rain, including some thunderstorms will prevail from later today through at least Monday. Heavy rain and a few severe storms will be possible overnight tonight and on Saturday. We may see a few breaks in between periods of rain, but the overall pattern will remain unstable and conducive for thunderstorm development for the next 3 days. Brisk southeast winds today have prompted a Coastal flood Watch with tides running about 1 1/2 feet above normal levels through today.
Storm development is not expected in the Tropical Atlantic Basin at this time.
