SYNOPSIS AND OUTLOOK:High pressure aloft will keep partly cloudy skies and hot weather around as we move through this week. Slightly deeper moisture over the area may set off a few showers today and tomorrow with rain chances increasing slightly as we near the weekend. Otherwise, expect mostly sunny, hot weather through tomorrow. p>NATIONAL OUTLOOK
This morning, a surface low is located over the northeast Gulf of Mexico near the remnants of an old frontal boundary. Elsewhere, a elongated cold front extends from California and Nevada to a low in Utah. The front then continues on east across the Rockies to the eastern and northern Plains to surface lows in the Dakotas and southern Canada. A warm front stretches from the low in the Dakotas eastward across the Midwest and Ohio Valley. Elsewhere, high pressure sits over Oregon.
At the upper-levels, we see a slightly more amplified pattern. A large high pressure ridge continues to extend north from Texas across the Plains to the Great Lakes and Canada. Far to the northwest, a low pressure trough is moving through Montana and Idaho, while far to the east a low pressure area over eastern Canada is generating a weak trough over New England.
Hot, mostly dry and sunny weather will continue for the foreseeable future, though each day will bring a slight chance of isolated thundershowers. Looking further down the road, the high pressure ridge over our area will gradually shift north and west while a low pressure trough deepens over the East. This may pave the way for more moisture and some rain as a weak cold front drifts into Southeast Texas towards the end of this week into the weekend.
The Tropical Atlantic Basin remains quiet overall and storm development is not expected at this time. A surface low in the northeast Gulf of Mexico shows little potential for development at this point in time.
