SYNOPSIS AND OUTLOOK:
An upper-level low and trough to our west continues to send weak disturbances over Southeast Texas as it tracks slowly east-northeast. Meanwhile, deep moisture at the surface and a stalled frontal boundary/wind shift line over the northwest Gulf of Mexico provide fuel for a continuing chance of showers and thunderstorms.
This morning, a stationary frontal boundary/wind shift line extends across the northwest Gulf of Mexico to the Florida coast where it becomes an active cold front attached to a low east of South Carolina. To our west, . The frontal boundary then curves eastward to a low in the Atlantic east of South Carolina. To our west, a surface low and trough is located over northern Mexico. Further west, a slow moving cold front is located over West Texas, northern Mexico and Arizona. Meanwhile, high pressure dominates the weather over the Mid-South and Midwest as well as over the Rocky Mountains and Desert Southwest.
At the upper-levels we moving back to a slightly more amplified flow with a high pressure ridge along the East Coast and extending westward into the eastern Plains A deep upper-level low and trough is located over the Desert Southwest and northern Mexico with a high pressure ridge developing along the West Coast.
Cloudy to partly cloudy skies and mild temperatures will prevail through Saturday as more in a series of upper-level disturbances track eastward into Texas. This will set the stage for more periods of showers and thunderstorms. We should see some drier conditions by Sunday with a weak cold front bring somewhat cooler night-time temperatures by Monday.
The Tropical Atlantic Basin remains quiet overall with no active tropical cyclones and tropical development not expected over the coming 48-hours.
