Late Tuesday PM December 13th Update – We Stay Quiet and Cold for Wednesday

Good Tuesday evening, everyone. It took some time over the past few days, but we FINALLY saw some sunshine today. After a cloudy and cold start this morning, we saw a break in the cloud cover during the afternoon. It was short-lived as clouds continue to work back in overnight. Even with clouds around, we’ll stay quiet on the radar below…

The cloud cover tonight will actually help us out. Instead of dropping down so much by sunrise, temperatures should hold pretty steady overnight. Even though we’ll be cloudy by the morning drive, we’ll have temperatures start in the middle 20s…

By late morning and into Wednesday afternoon, we should have some breaks in the cloud cover again. Even though skies should turn partly sunny, it won’t lead to much of a warm up. With a north wind at 5-15 mph, afternoon highs will top out in the middle 30s…

We stay cold, cloudy and quiet for Thursday as we watch out west for our weekend storm system to develop and move onshore. Have a look at where that system was late tonight on the surface map below…

setup

Even though the system isn’t onshore yet, some rain and snow have already worked into the Pacific Northwest. As you can see below, the system is still a good distance away. That means we’ll have plenty of time to see where the system moves onshore. Once that happens, not only will we have a good idea where it should track, the computer models will as well…

With the way things stand, we’ll still have plenty of cloudy skies with some slight rain chances as early as Friday afternoon and evening. Going into Saturday, we should have early AM highs in the middle to upper 50s before temperatures take quite a tumble. Depending on how fast temperatures drop, how the moisture with this system looks and where the system tracks, those are 3 key factors to watch. So far, Saturday morning could start with some rain chances that could start switching over to sleet before we hit the noon hour. Saturday afternoon should have any sleet switching over to snow. Before the system clears out, we could have snow Saturday evening and last into early Sunday morning…

Once we get well on the backside of this system, we’re still looking at quite a cold punch to start the new week. After lows drop into the single digits Sunday morning, we may not get out of the teens on Sunday. In fact, the GFS below wants afternoon highs close to 18°. The last time we recorded an official high of 18° was back on March 3, 2014…

Going into the middle of next week, we should trend back into 20s on Monday, the 30s on Tuesday and back into the 40s by Wednesday. For the latest on the long-range forecast and Doug’s latest thoughts on the pattern, he has you covered over on headypattern.com

Have a good night and a great Wednesday!

LONG RANGE FORECAST: Based off of the HP(Heady Pattern)

SLIGHT CHANCES:  MEAN IT IS A WEAKER SYSTEM THAT WILL GIVE US SCATTERED SHOWERS OR SNOW SHOWERS. 

IF I DON’T SAY SLIGHT:  THAT MEANS THIS IS A STRONGER SYSTEM

December 21st-Christmas Eve:  Milder temperatures return later on with rain chances by Christmas Eve and Christmas Day.

December 26th-New Years Eve:  A mild start to the week with rain and snow chances on Tuesday and Wednesday.  Cold and dry the rest of the week.

January 1st-8th:  A mild start to the week with slight chances for rain on Monday.  Then cold temperatures work in with slight chances for snow by Saturday.
