12/23 DC/MD/VA Weather Outlook

An active weather day with some severe weather possible. Heavy rains and wind the main story. Cold but snowless weekend and a turn to a milder pattern end chances of snow threats for a while.

 

Summary:

A strong cold front will cross the area today. Strong energy involved will cause some isolated thunderstorms. There is a lot of low level intability and if this were summer a great concern for tornadoes would exist, but concern today would mainly be isolated storms and some with strong winds. Mild highs today before the chill down for the weekend. As was noted in the last post, it seems abundantly clear that the +PNA pattern will break down for at least a week and above to even much above normal temperatures will become likely next week. I think the temperature forecast will be a bit of a challenge, and I may be too cool in my forecast, but we will see. Next slight chance of a cool down is around new years, and it will not be a sticking cold, but maybe a Cold Air Damming situation. But that will be watched. Appears a new pattern change could take a s long as January 10th timeframe before a significant cool down would occur.  

 

Forecast:

 

Today: SW: 55-65 SE: 55-65 N: 55-65

Windy with Rain, increasing and becoming heavy at times. Some thunder and isolated severe not out of the question.

 

Friday: SW: 40-50  SE: 40-50 N: 35 -45

Partly Cloudy. Snow showers possible early western facing Mountains.

 

Saturday: SW: 25-32 SE: 28-35 N: 20-30

Cold!

 

Saturday: SW: 30-40 SE: 35-45 N: 25-35

Continued cold,

 

Monday: SW: 40-50 SE: 40-50 N: 45-55

Some cloudiness, especially in the afternoon.

 

Tuesday: SW: 50-60 SE: 55-65 N: 45-55

Partly Cloudy

 

Wednesday: SW: 55-65 SE: 55-65 N: 50-60

Partly cloudy.

 

Long Term:

Like mentioned above, I see some possibilities of a Cold Air Damming situation next weekend, but that cold should be short lived and we will mild up again. Appears the bnext chance for a colder pattern will not arrive until around January 10th.

 

 

All for now!
