Warming trend starts today....
One more very nice cool morning underway with pre-dawn air temps in the 40s and 50s. However a rapid warming trend will kick in today and by the weekend near-record highs are expected.
Major pattern change is now underway with a major upper trough beginning to dig into the northwestern U.S. At first this will mean southwest flow aloft over our region, but by the weekend a strong upper ridge takes control of the eastern U.S....with record heat a likely result.
By Friday Heartland highs will sneak above 90°...and over the weekend mid-90s look possible along with dew points approaching 70°!
T'storms return?
Dry conditions are expected to continue into the weekend despite increasing heat and humidity, thanks to a strong ridge aloft. By Sunday afternoon but more likely on Monday the ridge should start to weaken enough for a few popup type storms..and then on Monday night or Tuesday the ridge breaks down with westerly flow aloft allowing a cold front to sweep through from west to east...this looks to be the next significant chance/threat of T'storms here.
Cooler again?
Longer range models continue to advertise a nice upper trough bringing a few days of cooler wx to our area by the first weekend of June.
