Good Wednesday to one and all. Today is shaping up to be a good old fashioned washout as a windy and wet low pressure center works through the region from the south. This is the beginning of a very active pattern that continues to see our step down into a wintry pattern for the month of December.

The rains today will be increasing this morning from south to north and will be heavy at times. You can track this impressive rain shield right here…



Amounts of a half to one inch will be possible in a lot of areas. Temps today will generally be in the chilly 40s but will rise toward the 50s in the south and east late in the day. Winds will gust up right on into tonight and Thursday.

Temps will come way down later tonight as we fall into the 30s by daybreak when leftover rain showers will mix with or change to snow showers and flurries. Temps for Thursday should hold steady throughout much of the day. Winds on Thursday will make it feel colder than the actual temp shows.

Friday will see a mix of sun and clouds with highs in the 30s again. There could still be a leftover flurry or two.

The weekend will start off with another system developing across the deep south and working toward the Atlantic coast. The models have been slowly trending west with the threat of snow for Saturday as both runs of the GFS are now on board with snow working into parts of the state. Take a look…

The NAM only goes out to Saturday morning but it appears to be agreeing with the GFS. Here is the simulated radar from the model for early Saturday…


Let’s see how this thing trends over the next few days as we still have some time to watch it.

Another big storm will likely roll our way at some point early to mid next week. We will tackle that in the coming days. The bigger picture for the month continues to point toward a very cold and wintry December as a whole for the country. The medium range forecast models will have all kinds of trouble dealing with such HUGE atmospheric changes in the coming days. Take a look at the various forecast indicies…



All four of the major indices I look at are screaming COLD and are doing so very loudly!! The Arctic Oscillation (AO) is off the charts negative and I don’t know that I have seen it forecast that low. If you have been reading the blog… you know that the AO has been driving our pattern since the spring. Everytime it went negative… we got cold and in some cases this summer and early fall… record breaking cold. Now… throw in a -NAO… -EPO and a +PNA and you have the makings for something extreme happening across the country this month.

I will update the short term a little later today. Have a great Wednesday and stay dry! Take care.
