     It's another sunny, warm afternoon courtesy of surface high pressure over the eastern US today. Forecast will be dry and not as cool tonight. High pressure ridging will slide east overnight allowing for warmer & more humid air to infiltrate our area from the southwest. We'll see temps leaning towards the upper 80s & a small chance for an afternoon shower or thunderstorm both Wednesday & Thursday. Friday and Saturday are looking generally dry. But warmer temps & higher dew points may trigger a stray afternoon shower or thunderstorm, especially in our mountain counties. We may need the rain gear for kickoff as cold brings rain Saturday night/Sunday.

     For the rest of today...surface high pressure hangs on to make for a sunny day today. Warmer air lifting north with bring slightly warmer temps for today and tonight. Look  for highs today in the low/mid 80s.

     For tonight...not as cool tonight as last night. Lows will be in the mid 50s with some broken clouds moving in after midnight. Light fog will develop in a few spots by Wednesday morning.

     Otherwise, Wednesday will start sunny with temps reaching the mid 80s again. Increasing afternoon/evening clouds are expected ahead of a weak frontal boundary timed for Wednesday night/Thursday. There's a small chance for a few scattered showers & an isolated storm Wednesday night through Thursday afternoon. More humidity and noticeably higher temperatures are in store towards the end of the week.

     We'll see a sun/cloud mix and an isolated afternoon rumble of thunder Friday and Saturday. Then a cold front will send another shot of rain over our area Saturday night & Sunday.

      On the tropical front...the Gulf of Mexico will raise a few eyebrows over the next few days as an area of low pressure brings a chance for storms & several inches of rain to the Texas/Louisiana area. Model guidance is split down the middle as to whether this scenario will be realized...Also another tropical cyclone may threaten the east coast of the US by the middle of next week. Tropical Depression # 12, still out in the middle of the Atlantic Ocean was upgraded to Tropical Strom Katia last night. Further strengthening is expected in the coming days as she grazes the northern Leeward Islands. Will report of the progress of this storm it develops!

     Nearly 9 inches of rain would be a welcome prospect in Texas...Click to enlarge photo!
