Wild winter pattern setting up.

We have a lot to talk about in the world of weather. Can you believe this is our first active and cold January in four years! We are due, and we may pay dearly for missing out on the last 3 January's.

Icing potential Sunday morning.

First off we have a Winter Weather Advisory in effect until noon Sunday for areas of freezing drizzle. We are most concerned about areas around and NW of I-84. Everyone will be above freezing this afternoon and evening when a round of rain ushers in some bitter cold temperatures after midnight Sunday night.

Bitter cold Monday Tuesday Wednesday.

After the rain Sunday night, wind chills will drop to 5 -15 degrees on Monday, this will be the coldest day of the season. Areas of scattered snow squalls will arrive Monday afternoon and evening bringing another reinforcing shot of even colder air. This one will really hurt as actual temperatures will drop below zero inland with wind chills between -10 and -20 degrees. The afternoon high temperature Tuesday may not make it above 10 in some towns. We slowly moderate by Wednesday and the rest of the week.

Medium to Long Range 5-15 days look stormy.

We have quite a few storm chances starting later this week. It is too early to pinpoint any specifics, here is the set up. With an upper air pattern like this, there will be several storm chances with plenty of cold around.

We have a ridge setting up over the Western US called a +PNA and Alaska -EPO (notice the oranges and reds along the west coast and Alaska, this is a monster ridge. This will allow cold air to funnel into the eastern US and combined with an east coast trough (blue over the east) will allow for a storm track up the east coast. There will also be some transient periods of a -NAO which is a blocking ridge in Greenland (oranges and reds north east of Canada). Having a -NAO guides storms to a more favorable track for north east snow storms and also can slow storms down allowing for longer duration storms.

Here are the dates of interest

Friday January 14 - Watching developing storminess to our south that may try to retrograde west to New England. Low chance of impact.

Sunday/Monday January 16/17 - Watching a potential "Miller B" low form. We use this term when a storm system coming from the west transfers energy to a Nor'Easter off the East Coast. We are very confident in a storm, however there is no confidence in what kind of impacts we will see. Some guidance is showing a very strong storm system, we will watch this closely. Medium confidence of storm impact. Notice all the L's south of New England on our European ensembles.

January 21-23 would be the next threat.

Stay tuned!
