Wednesday Evening Weather Update - Like the cool weather??

---------------------------------FORECAST-----------------------------------

TONIGHT - Cold WATCH for frost, lows in the low to mid 40's, winds dying down though will make it not as bad. Clear.
THURSDAY - Highs in the high 60's, a tad warmer then today. Nice day, clear, not as much wind at all.
FRIDAY - A tad warmer, highs around 70°, watch out for some clouds...not too bad though. Nice day. Clouds getting thicker at night as a very weak frontal system moves through.
SATURDAY - Highs in the mid 70's, cloudy with showers in the morning and maybe a t-storm or two during the morning into the afternoon...not much though.
--------------------------FORECAST DISCUSSION------------------------
Now was that temperature contrast or not! We reached 83.6° Yesterday, and only 64.3° today - that is over a 19° difference in less then 24 hours!
Now, lets enjoy it...cooler weather, closer to average will be sticking around for the next couple days and into the weekend. High pressure will continue to build to the west of us tonight and move over us tomorrow into Friday. Watch for those clouds forming Friday afternoon as a weak area of low pressure/frontal system moves closer into the night. Showers and maybe a t-storm into Saturday afternoon cannot be ruled out. Models are sticking with the precipitation staying to the north of us as the warm front moves through..we shall see. GFS does want to build things up a bit, showing CAPE 1500-2200 during the day Saturday and a good amount of instability for the afternoon into evening in terms of t-storms, but lets see what the ridging does to try to stop that. Likely, if a cell does form FRIDAY NIGHT, it will be mostly quick bursts of heavy rainfall as storm motion very slow and now that much convection going on. Saturday the storms look a bit quicker and uplift/dynamics a bit better to produce less rain but maybe more thunder if something develops.
Highs pressure will again build Sunday into Monday as High Pressure builds from the Canadian Maritimes, a bit more humid air but cooler as well. Next system likely Tuesday-Wednesday and this could be a nice bout of rain as a cold front moves through and an organized low tries to develop to the south of us and come north....lets wait and see what happens with this.
We need rain, right now we have had no measurable rain for this month, and in April ended with 71% of normal Precipitation. The Palmer Drought Index for our region is at -3 anomaly, and precipitation is 4" below normal for the period March through May 8th.
Have a great night guys!
