TEMPERATURES WILL TAKE A PLUNGE AS A VERY CHILLY AIR MASS MOVES IN ON MONDAY… IN THE MEANTIME, THE WEEKEND WILL BE ABOVE NORMAL WITH DRY CONDITIONS

2011 will end on the mild side but Old Man Winter is getting ready to show his muscle with dropping temperatures early next week.  By Tuesday, high temperatures will probably not rise above the 30’s. Winds will be a factor, also. Does this mean that the mild weather pattern is over? I don’t think so. Temperatures are expected to moderate later next week. One factor that can create a very cold and sometimes stormy weather pattern here in the eastern part of the nation is a blocking pattern. One example of a blocking pattern is a large high pressure system over Greenland that is basically stationary. This high causes the upper-level winds (or the jet stream) to buckle and become more amplified over North America. Upper level winds then blow from Northern Central Canada south to the Gulf Coast and then turn back northeast along the East Coast. This pattern normally with the deep trough just to our west creates huge snowstorms along and near the East Coast. We haven’t seen that this year which is very different from last year, which was very stormy and cold. This year, the Arctic air masses have been locked in northern Canada. There are other factors that play into creating a stormy weather pattern such as the Artic Oscillation phase. You can search for that on the Internet for more information to better understand this climatic pattern…. So, enjoy the mild weather while it lasts and Happy New Year!

A WARM UP IS ON THE WAY, BUT COLDER AIR IS EXPECTED AFTER THE NEW YEAR… NO SIGNIFICANT PRECIPITATION IS EXPECTED OVER THE NEXT FEW DAYS

Well, I just got back from visiting friends and family up in NJ and PA. The weather up there this year was very different from last year. We saw no snow on the ground anywhere we traveled, and that included the Wilkes-Barre area in Northeastern Pennsylvania. Last year, I had to dig out from 33 inches of snow in Bayonne, NJ. That was an incredible blizzard that crippled parts of the Northeast the day after Christmas… The only bad weather we encountered this year was just some rain. Speaking of rain,  I checked my rain gauge and around 0.60 inches fell in my Virginia Beach backyard. When we left PA this morning, the temperature was around 15 degrees…. The weather over the next few days will feature mild temperatures and we should not see any significant precipitation through New Year’s Day at least. Enjoy the dry and above normal conditions as it appears a major drop in temperatures is expected after the New Year.

AFTER A CHILLY WEEKEND, ANOTHER WARM-UP IS ON THE WAY, ALONG WITH AN INCREASED CHANCE OF WET WEATHER BY MID-WEEK

The weather pattern across the Eastern part of the nation is relatively quiet this Sunday morning. The national radar shows very little precipitation falling across the United States. Speaking of precipitation, about a quarter of an inch of rain fell in my backyard on Friday night. The cold high pressure area is going to slowly lose its grip on the Mid-Atlantic states over the next few days and forecasters expect a fairly decent warm-up to set in by mid-week. A frontal system moving into the region may bring us some rain/showers sometime between Tuesday night and Thursday morning… One thing to note this month is the lack of snow cover in the Eastern part of the nation. This has impacted many of the ski resorts in the East.  This is nothing like last year when conditions were cold enough on most days to make snow and they were receiving snow from Mother Nature, too. Will the weather pattern change in the near future? Right now, from what I’ve seen, there are no definitive signs of a major pattern change that would bring a major cold spell and/or snowstorm to the Mid-Atlantic States over the next week or so. That means that there won’t be a white Christmas this year for Hampton Roads… Thanks for reading and have a great day.

CLOUDS INCREASE FRIDAY AFTERNOON WITH RAIN EXPECTED TO MOVE IN FRIDAY NIGHT… WEAK LOW PRESSURE QUICKLY MOVES OFF THE COAST SATURDAY MORNING… COLDER WEATHER IS ON ITS WAY FOR SATURDAY AND SUNDAY

A cold front is now (Friday evening) draped over the area with a weak low pressure system expected to develop on the front and move quickly eastward off the coast Saturday morning. Rain is expected to overspread most of the area this evening but it should be out of here Saturday morning. Rainfall amounts are expected to be around a third of an inch. Cooler air moves in for the weekend with temperatures not expected to get much above 50 degrees. Temperatures may stay in the 40’s for much of the afternoon on Saturday. Although it may seem quite cold on Saturday, temperatures will be only slightly below normal for this time of year. It has been quite mild this month unlike December of 2010, when it was much colder. Early next week, temperatures are expected to come up a bit and there may be some showers sometime during the mid-week period.

I’ll have an update on Sunday morning.

THE WEATHER THIS WEEK SHOULD BE RATHER UNEVENTFUL… AFTER A CHILLY WEEKEND, A SLOW WARMING TREND WILL SET IN… NO SIGNIFICANT PRECIPITATION IS EXPECTED FOR MOST OF THE UPCOMING WEEK

The weather across most of the nation is fairly quiet this Sunday morning. There is some shower activity expected from Florida westward to the Gulf Coast as the clockwise flow around a high pressure area centered over the Ohio Valley brings Atlantic and Gulf moisture inland. Some parts of drought stricken Texas will see beneficial rain from this weather pattern. That high pressure is going to bring us a dry period of weather that should last most of this week. There may be a shower later in the week when a cold front approaches, but forecasters do not believe that there will be any significant precipitation this week… Since 2011 has brought so many major weather events to various parts of the country, it’s nice to see this period of quiet weather. But keep in mind, it is December, and we all know that Old Man Winter will be making his presence known very soon. Have a great day and thanks for reading.
