SYNOPSIS AND OUTLOOK:
A line of thunderstorms is pushing south through Southeast Texas this morning and will bring rain and gusty winds to Galveston County. Rain chances should diminish later today. The storms are being produced by a short-wave trough moving east through the area tomorrow. Rain chances will linger into Friday as another short-wave low pressure trough moves east into the center of the country by the end of the week.
This morning, an outflow boundary/ wind shift line is moving into Southeast Texas accompanied by gusty winds and brief, heavy rain. Meanwhile, a weak high pressure area sits over North Texas while low pressure continues over West Texas. Elsewhere, a cold front is moving south into the central Plains and upper-Midwest. High pressure is located behind the front over the central plains with high pressure also noted over the central and northern Rockies.
At the upper-levels, we find a mildly amplified flow with a high pressure ridge along and off the U.S. East Coast, short-wave low pressure trough over the eastern Plains and another short-wave low pressure trough tracking eastward through the western third of the country.
Although rain chances will be decreasing as we move to the end of the week, the chance of showers and thunderstorms will continue each day as the upper-level troughs slowly shift east, deep Gulf moisture continues to flow into the state, and daytime heating contributes to the develop of some showers and thunderstorms. Otherwise, expect partly to mostly cloudy skies and warm temperatures.
The Tropical Atlantic Basin remains quiet overall and storm development is not expected at this time.
