High pressure will dominate the eastern half of the U.S. today and for the early part of the week. A strong northerly flow at the surface, and in the upper levels will keep skies clear and temperatures below normal. Lots of sunshine is expected today, but the sun won't be able to warm things much because of the movement of the colder air. Also, expect winds to be in the 15-20 mph range, keeping wind chills well below the actual temperatures.
Temperatures will hover in the lower 50s for highs, with upper 40s over the extreme northern sections. Winds chill values will run in the low 40s most of the day. The center of the high pressure ridge will slide over the southeast tonight. This will lower the wind speeds, and with clear skies, lows will drop into the upper 20s north to the lower 30s south. Expect a light freeze along and north of the I-10 corridor, with frost likely area wide.
More sunshine is expected tomorrow with slightly warmer temperatures. A trough will dig over the western states by the mid week helping to develop a surface trough over the plains. This next system is expected to bring clouds back into the region by Wednesday, and rain more likely on Thursday. Models are predicting some storminess, but it appears this next system will move fairly quickly and be heading eastward by Friday. This should set up a fairly nice weekend with normal temperatures.
