Overnight Update

Cold and dry air will move very slowly into northern Virginia overnight, reaching a line just north of Fredericksburg to Charlottesville by sunrise. Rain will overspread the area after midnight, with a few thunderstorms possible across the VA/NC border. Richmond will only see a cold rain from this event, with temperatures ranging from 36 to 40 degrees for the balance of the day. Meteorologist Carrie Rose will have the latest look at the weather situation at 5 AM on CBS 6, and here on the CBS 6 Storm Team Blog.

Freezing Rain Possible

A strong storm system will continue to track through the U.S., bringing freezing rain to the Southern Plains Monday. Light ice accumulation is occurring in North Texas and Southern Oklahoma, with a freezing rain/sleet mix farther northeast into Arkansas and Tennessee.

This precipitation hugs the strong cold front that stalled in the Deep South Sunday, after bringing 30 degree temperature drops to much of the Southern Plains. For example, Dallas, TX had a high of 84 degrees on Saturday, then fell to 37 degrees by Sunday night. Temperatures continued to fall and hover around freezing Monday, with freezing rain falling. Check out some of the record highs set Saturday, January 3, 2009 ahead of the cold front:

Dallas, TX: 84
Shreveport, LA: 81
Longview, TX: 81
Tyler, TX: 80
Texarkana, AR: 79
Tulsa, OK: 78
Little Rock, AR: 77
Fayetteville, AR: 74


Parts of Virginia are expected to receive some of this freezing rain and sleet over the next couple of days, starting early Tuesday. We will be watching this system closely because of the potential for icing in the mountains west, as well as in Central Virginia. Temperatures will be in the 30's much of Tuesday, so any locations that get at or below freezing at the surface, will have freezing rain. Sleet may also mix in with the rain at times.

This week does appear to be a sign of things to come, setting up the weather trend that will likely continue in the coming weeks. This setup could lead to several opportunities for winter weather in rapid succession. We'll be monitoring all of these changes closely and keep you ahead of the storm!

Big Changes Ahead

We are tracking a potent storm system headed this way for Tuesday and Wednesday. You can find all the details about this storm in my forecast discussion by clicking the "7 Day Outlook" link at the top of the page.



This storm will be approaching our area from the southwest. Afterwards, we will experience a major shift in our weather pattern where the jet stream will become highly amplified. There will be a bulge, or "ridge" developing along the west coast. Conversely, a pronounced dip, or "trough", will develop in the east coast.



In this type of scenario, the majority of our storms will move in from the northwest out of Canada...called "clippers". These type of storms will keep things cold for the middle of the month. They will also bring quick chances for wintry weather.



In other words, the mild and wet weather we experienced in December will be loooong gone. It will be interesting how long we will be stuck in this cold weather pattern. A mild La Nina developed during late December and could strengthen through this month. If this is the case, then it could be a dry and mild finish to this winter!
