.DISCUSSION...

...Hot/dry Tuesday and Wednesday...

Isolated thunderstorms are possible this afternoon and early
evening, but this activity will be weaker and less widespread than
Sunday`s storms. Tuesday and Wednesday are on track to be hot
(triple digits expected) and dry (RHs down to 10%) as strong high
pressure aloft builds over the region. A low level jet will bring
25-35 mph gusts to higher hills in eastern zones Tuesday night.
Look for deeply mixed winds gusting near 20 mph Wednesday. Also,
cannot rule out a few high-based thunderstorms late Wednesday. A
dry cold front is expected to arrive late Wednesday night into
early Thursday, bringing cooler temps and higher humidities to end
the week. JKL
