SYNOPSIS AND OUTLOOK:
We remained sandwiched between high pressure aloft to our west and low pressure aloft to our east. Weak low pressure over North Texas and the trough to our east will continue to give us a chance at a few showers or thunderstorms today, with chances decreasing on Sunday into Monday.
This morning, high pressure is ridging west into the Gulf of Mexico from Florida and the Atlantic. Elsewhere, a couple of surface lows are situated along the Red River on the Texas/Oklahoma border. Elsewhere, a mostly stationary frontal boundary stretches east and northeast from northeast Oklahoma across the Mid-South to lows in Pennsylvania and Virginia. High pressure is located behind this front from the Four Corners region of the West to the central Plains and upper-Midwest. To the west, areas of surface low pressure continue over much of the western third of the country.
At the upper-levels, we still see an amplified flow. A broad low pressure trough is in evidence from the Great Lakes to the southern Plains and North Texas. Further west, a large high pressure ridge dominates the weather over the western third of the country.
Although rain chances will continue today, the long-term outlook is for less rain and hot summer conditions as we head into next week as high pressure generally prevails over our area. Moist air flowing in off the Gulf of Mexico and the upper-level trough to our north and northeast may set off thunderstorms today, but generally we are looking at plenty of sunshine and typical early July weather.
The Tropical Atlantic Basin remains quiet overall and storm development is not expected at this time.
