Weather It Is (Hold Your Hats)

Good Evening:

After a blistering (actually just hot) day, we're headed on a steep slope to winter.  Temperatures will drop 10 or so degree tonight and tomorrow temperatures will rise only to about 20 C in the higher elevations and low 20s in the central plains.  

The winter-like air is courtesy of a high pressure/low pressure combination.  High pressure is located to our north and the relatively cool air flowing to the south helps to periodically spin up a low pressure area.  When the low pressure moves by, the winds switch to the west and north drawing in the cool air.  However, ahead of the low, the winds are more easterly and it warms up quite suddenly and feels a lot more like summer.

We'll have another strong upward tick in the temperatures in time for Shavuot, but then head back down again right after as another low moves in.  These low pressure areas are moisture starved, so we don't see anything more than a light shower with them (did you smell the rain this morning?). We still don't see any real summer on the way.
