LOW PRESSURE MOVES AWAY ON MONDAY… WEATHER CONDITIONS SHOULD BE DECENT THROUGH MID-WEEK WITH TEMPERATURES RUNNING AT OR SLIGHTLY ABOVE NORMAL… LATER IN THE WEEK, TEMPERATURES TREND DOWNWARD ALONG WITH A CHANCE OF RAIN

The storm system that moved through Hampton Roads on Sunday brought 1.20 inches of rainfall to my neighborhood. The rain that fell in the morning totalled 0.75 inches and then it rained again during the evening hours which totaled around a half inch. The afternoon turned out quite nice with the sun coming out and temperatures shooting up into the 60’s in some areas. That storm system is moving off the coast and it is intensifying. This is causing our winds to be quite gusty today. Temperatures will be seasonal (or slightly above seasonal norms) today and this should be the case through mid-week as high pressure buids back into the region. Later in the week, forecasters will be watching a storm system that may bring rain to our region Thursday night and Friday. Although it is expected to turn cooler later the week, forecasters don’t expect that we’ll have any frozen precipitation from this system. However, areas well to our north and west may have some snow or ice so stay tuned… The weather pattern seems to be returning to a more wetter pattern again as it was during this past autumn. El Nino is most likely playing a role and it is likely that we’ll see this continue for the remander of the winter season. Note that the west coast is about to get bombarded with several storm systems that may produce flooding, mudslides, and high winds. El Nino winters can be very storm on the west coast.

SUNDAY MORNING DAWNS WET AND WINDY… CONDITIONS SHOULD IMPROVE LATER IN THE DAY… MONDAY LOOKS LIKE A DECENT DAY FOR THE MIDDLE OF JANUARY… THE AIR BEHIND THIS SYSTEM IS NOT THAT COLD SO FORECASTERS DON’T SEE A RETURN TO FRIGID TEMPERATURES THROUGH AT LEAST MID-WEEK

As I write this, it’s raining and the winds seem to be increasing a bit out of the southeast. The rain is expected to continue most of the morning but if you look at the radar and satellite pictures, there is an abrupt end to both the dense overcast as well as the precipitation which is not far to our south and west. This should move into the Hampton Roads region this afternoon and as a result, we may actually see some sunshine today. However, there will still be a chance of a lingering shower or two. There is a new low pressure system developing over the Caronlinas which will replace the initial low as the primary low pressure center. Once the low moves past the area, our winds will switch around to the southwest and then eventually the west. Temperatures will be quite mild, especially across NC.  Monday should be a fairly decent day as there really isn’t any chilly air behind this system. Tuesday and Wednesday should also be uneventful but as we head into Thursday, another system may approach the area producing rain or showers. This is our first significant precipitation event in 2010 and it will be interesting to see if the wet weather pattern will continue. El Nino is still out there in the Pacific so odds are it will continue to be on the wet side. The West Coast is about to receive a lot of rainfall over the next week or so, which is a normal for an El Nino winter. Let’s hope that this doesn’t result in mudslides and flooding but history shows that El Nino winters are notorious for numerous problems in California. So, enjoy the milder weather (once the rain stops) and get out there if you can. We still have plenty of winter to go.

RAIN IS ON THE WAY BUT WE SHOULD SEE A NICE SATURDAY… SUNDAY LOOKS WET BUT TEMPERATURES WILL BE ON THE MILD SIDE

A low pressure system in the Gulf Coast region will move northeastward over the weekend bringing a good chance of a significant rain event for Hampton Roads. The rain will most likely begin before dawn Sunday morning, but keep in mind, the models do not agree on the timing of this event. One model (GFS) is much faster with the rain. Either way, Sunday looks like a wet day and there may even be some thunder in the southeastern portions of the area. Temperatures will be on the mild side during this event so precipitation type will not be an issue. The rain should end later Sunday as the low pulls away… I hope that you had a chance to get out and enjoy the milder temperatures on Friday. The prolonged cold spell had us all bundling up and many of us spent as little time outdoors as possible. Saturday will be cooler near the water as our winds will be onshore, which hasn’t been the case in quite a while. I’ll have an update on Sunday morning.

THE COLD SPELL IS JUST ABOUT OVER… A STORM SYSTEM MAY BRING US SOME RAIN ON SUNDAY

This has been one of the most prolonged cold spells that Hampton Roads has seen in quite a while. Temperatures have been below normal nearly continually this past few weeks. Well, it appears that a change is about to take place. The weather pattern is about to change which will allow milder air to move into our region. Just a return to normal temperatures will feel like spring is here. Our normal high temperature is 49 degrees. Meanwhile, a low pressure system affecting the western part of the nation will move southeasward into the Gulf of Mexico where it will reform. This low will eventually pull out of the Gulf Coast states and move northeastward. The exact track is not certain at this time but the thinking is that we will see some rain beginning Saturday night or early Sunday. Will we see a return to the bitterly cold weather pattern anytime soon? I don’t think so. Arctic air will be building again in Northern Canada but I don’t think that this air will plunge into our part of the nation anytime soon.

THE FRIGID AIR MASS WILL RELEASE ITS GRIP ON THE MID-ATLANTIC STATES… NO SIGNIFICANT PRECIPITATION IS EXPECTED FOR THE NEXT FEW DAYS….

In my opinion, the most striking thing about this morning’s (Sunday) weather map is the lack of precipitation across the United States.  The large high pressure system that has brought the frigid air down from Canada has scoured out the moisture from the Rockies on east to the Atlantic Coast. Weathermen across the eastern third of the nation are getting some welcome rest as there is nothing to worry about for most localities here in the Mid-Atlantic states until we get to later in the week, when forecasters will be watching a possible southern storm system develop. More on that later. The frigid air mass currently in place will slowly release its icy grip on the Mid-Atlantic states early this week. There is even the possibility that by late in the week, temperatures may be flirting with the 50 degree mark. That’s going to feel good! Aside from a few flurries or snow showers, there should be no major weather concerns through mid to late week.  Models are now indicating that a low is going to form somewhere near the Gulf Coast by late in the week. This system may be a big player in the weather across the Mid-Atlantic region by the weekend. The timing of this system is very much in question right now, and it is far off in the future. Remember, the El Nino is still out there so I don’t expect our dry weather pattern of late to continue too much longer.
