Heat advisories up for Tuesday - not sure why they didn’t automatically extend through Wednesday. .

I think they're going to hoist an Excessive Heat Warning for Wednesday later today or tomorrow.

Several of our valley locations this morning saw lows down into the 50's with the ridges remaining in lower 60's. The lowest I could find was 56.3 at the Warwick DEOS. Today will be our 6th below normal temperature day over the last 8 days. We turn that around tomorrow with highs well into the 80's with 90's in the valley spots. Widespread 90's on Wednesday before we back off several degrees by Thursday. So not many spots across Chesco will get to "enjoy" the so called "heat wave" this week. By next weekend we return to near normal temperatures with increasing chances of some showers.

Also interesting that according to CTP's morning graphics that York and Lancaster counties are to have the LOWEST Heat Index values tomorrow in their forecast area. On Wednesday, York and Lancaster will be the highest.

It's the element of surprise. Just like winter snowstorms you go to bed feeling confident that NWS has an advisory out for 1 to 3 in of snow tomorrow. But you wake up tomorrow morning and it's a winter storm warning for 10 to 14 inches.
