SYNOPSIS AND OUTLOOK:An influx of deeper Gulf moisture and a weak frontal boundary drifting south over North Texas will give us a chance at a few scattered thundershowers later today and tomorrow. Otherwise, expect more sunshine and hot weather. p>NATIONAL OUTLOOK
This morning, an elongated cold front extends from southern Nevada eastward across the southern Rockies to a low south of Wichita Falls. The front then continues on east and northeast across the Mid-South and Appalachians to eastern Canada. To the east, surface lows persist over southwest Georgia and in the Atlantic southeast of South Carolina. Elsewhere, high pressure sits over Montana.
At the upper-levels, high pressure continues from Texas northeastward across the Mississippi River to the eastern third of the U.S.. To the west, high pressure is also developing over the western third of the country. To the north, a low pressure center is located over Canada with an associated trough dipping south into Minnesota and Wisconsin.
Rain chances will improve slightly today into early Saturday as deeper moisture and a frontal boundary to the north provides somewhat better conditions for thundershower activity. Dry air is expected to creep back in over the weekend, ensuring a return to hot, mostly dry and sunny weather.
A tropical wave in the far eastern Atlantic is being given a 30% chance for development over the coming five days while a low off the coast of South Carolina is being given a 10% chance for developing over the coming five days. Otherwise, the Tropical Atlantic Basin remains quiet overall and storm development is not expected at this time.
