Classic August heat settling into the Carolinas...

Good Friday evening, the weekend is here! And so is your classic August heatwave...



You probably noticed today that is was quite toasty and no doubt it was. High temperatures recorded today were in the low to mid 90's on those warm bank thermometers. This looks to be the routine through most of the current 7-Day forecast.





High pressure aloft is building in to the Southern tier of the US, it will initially be centered across Texas and the Southern Plains where widespread 100 degree heat is expected in that part of the nation this weekend.







The heat will only continue to grow as we depart the weekend and head into early next week. By Tuesday, the heat ridge will shift east and strengthen a bit...that will lead to some of the hottest days coming up in the 7-Day forecast. With high pressure and downsloping winds, mid to a few upper 90's can't be ruled out, specially on Tuesday. Our current 7-day isn't quite as bullish for that timeframe but if model trends continue, we'll adjust the forecast accordingly.


At this time I don't expect the pattern to support 100-degree heat in or around the coverage area, normally to get that you need heights in the 594-597 dm range for that...but feel confident in some temps in the 94-98 degree range depending on local terrain effects...








Once we get toward the end of the current forecast period, the pattern will switch up again as the Southeast Ridge will retrograde itself back toward the Desert Southeast meanwhile the Western Atlantic Ridge will try to invade from the east. The Southeast will ultimately end up in a weakness between the ridges with a slight positive tilt trough axis running west of the Appalachians.




In simple terms...that should yield higher humidity and increased chances of convection...





Until then it will be dry over the next seven days, as you can see on this image the precip anomalies will be spotty to say the least...














Final graphic is a model generated temps for Morganton and Shelby through the forecast period...the ensemble data looks to be lining up well with the upper level weather pattern. The highest temps occur the first half of the week with a backing off of the heat for the second half next work week...
