This morning, surface low pressure is found west of Brownsville and near El Paso. Further north, a mostly stationary cold front continues from Southern California to lows over Utah, western Kansas and western Iowa. From there, the front continues on eastward across the northern Midwest to Pennsylvania, New Jersey and the Atlantic off the coast of New England. High pressure is found behind this front over Canada. Closer to home, a weak coastal trough and mid-level low is bringing heavy rain to the Texas coast. Elsewhere, high pressure is located in the Atlantic north of the Bahamas, while isolated lows continue over Northern California and British Columbia.
At the Upper-Levels, a mid and upper-level high pressure ridge is in control over much of the eastern half of the United States, while a mid to upper-level low continues along the South Texas and Mexican Gulf coasts. Further west, a large upper-level low is centered over Idaho with an associated low pressure trough digging south to Arizona and Southern California.
A weak low pressure trough, interacting with a mid and upper-level low, along and off the Texas and Mexican coasts is accompanied by a surge of deep Gulf moisture. There will be a good chance of significant rain today into Wednesday or Thursday. Clouds and rain chances will gradually decrease as these systems drift west and south and we return to a more typical June pattern by this weekend with more sun and only isolated thundershowers in the picture locally.
TROPICAL OUTLOOK:Tropical storm development is not expected at this time.
