THE WEATHER THIS WEEKEND WILL BE VERY NICE WITH PLENTY OF SUNSHINE… TEMPERATURES WILL TREND DOWNWARD LATER THIS WEEK

Yesterday (Friday), Norfolk International Airport recorded a record high temperature of 79 degrees! That was before the line of thunderstorms moved through. Virginia Beach picked up a little over a half inch of rain and there was more in some isolated spots. No tornadoes were reported here locally but out to our west severe weather did cause some damage. The weather this weekend will be tranquil in comparison. We should have lots of sunshine and pleasant temperatures for this time of year. The low pressure system that caused blizzard conditions in the Northern Plains states and the heavy rain and severe weather in some areas is now centered north of the Great Lakes… You may have heard reports that the Polar Vortex is going to drop southward next week. Computer models indicate that a return to below normal temperatures is likely by later in the week. There may be another round (or two) of snow in parts of the Northeast and possibly the Northern Mid-Atlantic States. It’s way too early for any details on the potential storms but I think that most meteorologists will agree that our spell of mild weather will be coming to an end. So, enjoy this weekend and get outdoors! As I said in my earlier posts, late February and March are very changeable with large swings in temperatures. It can also be a very windy time of year due to the strength of the weather systems and also the increasing sun angle, which increases atmospheric instability during the day…. California may be picking up some much needed rainfall this upcoming week and it may occur further south than the previous storms. That is very good news. However, it will only be a drop in the bucket as the drought there is severe. Time will be running out for them as their rainy season will be ending in about six weeks or so. Let’s hope they get several opportunities to put a dent in the incredible drought. No drought for us as our precipitation is running above normal this year so far. That’s it for now.

ARE YOU READY FOR WARMER WEATHER? A MAJOR CHANGE IN THE UPPER-LEVEL WIND PATTERN WILL BRING WARMER TEMPERATURES… THE PATTERN REMAINS SOMEWHAT ACTIVE

For the last several weeks, a long-wave trough in the eastern part of North America has brought repeated blasts of Arctic air into the East and also helped produce ideal conditions for cyclogenesis resulting in occasional storminess. The upper-level wind pattern has flattened and become more of a zonal flow, which means that the winds are blowing more west to east in general. Instead of the winds blowing from the Canadian tundra, air masses will be coming in from the Pacific Ocean. This will result in much milder weather, but it seems that the pattern will remain somewhat active with occasional frontal passages bringing rain/showers every so often. We still have to get through another very chilly day today (Monday, 2/17). A frontal system will be moving through tonight and early Tuesday may cause some showers and we might even see some sleet in some places. Frozen precipitation is likely further to our north as they see yet another winter weather event. Snowfall totals in many locations in the Northeast have been incredible this year. The change in the jet stream should bring relief for them, also. Will the pattern return to the cold and stormy pattern again before winter is over? I can’t say for sure, but what I do know is that we will get a well-deserved break later this week. Keep in mind that with the increasing daylight hours and the sun’s position getting higher and higher in the sky, our average temperatures are now slowly rising. You also have to keep in mind that late February and March can be a very volatile time of year.

INDICATIONS ARE THAT THE WEATHER PATTERN IS GOING TO CHANGE LATER IN THE WEEK… TEMPERATURES MAY BE ABOVE NORMAL FOR A CHANGE… AN INTENSIFYING LOW PRESSURE SYSTEM WILL BRING US SOME RAIN ON SATURDAY (2/15)… SUNDAY WILL BE DRY AND CHILLY

Are you tired of the winter? Well, hang in there, because current indications are that things are about to change and possibly in a big way. That’s not to say that we’re going to see an early spring. It just means that the weather pattern is finally going to change so that we are not seeing repeated blasts of cold air into the Mid-Atlantic states with storms in between bringing rain and sometimes snow. The upper-level wind pattern has been highly amplified bringing Arctic air masses south into the nation. The large trough over Eastern North America has caused unprecedented storminess over the Eastern third of the nation. We have another storm system sliding east that will intensify rapidly as it moves northeastward away from our region. Rain is expected to develop this morning. Winds will pick up later on as the storm begins to ramp up. It is expected to bring near blizzard conditions to parts of New England. Bombogenesis is expected to occur with this system. (See my Weather Fact on Bombogenesis). Sunday looks like a decent day for mid-February here in Hampton Roads but it will be on the chilly side. As next week progresses the upper-level wind pattern should bring us milder temperatures but there is still some uncertainty about the specific details.

THE WEATHER PATTERN REMAINS QUITE ACTIVE… CLOUDS DOMINATE THE SKIES ON SATURDAY AS A LOW PRESSURE SYSTEM DEVELOPS OFF THE CAROLINA COAST… IT’S A VERY CHALLENGING FORECAST FOR NEXT WEEK

Sunshine has been quite rare this past week. Yesterday (Friday), we saw the most sunshine than we saw in quite a while. We’ve been in a very active weather pattern resulting in above normal precipitation and it’s been quite chilly. The only good news is that today (Saturday) the chance of rain has decreased somewhat as the heaviest rainfall should stay just south of Hampton Roads. Low pressure is developing to our south along the coastal Carolinas and it will intensify as it moves northeast today and tonight. Areas to our north and west may actually get a little snowfall today from another disturbance that is weakening. Sunday should be a decent day for this time of year with temperatures near normal. Some sunshine is expected. Then the forecast gets real tricky. We should see a couple of opportunities for precipitation next week and there is a chance that it could be snow or sleet in some areas. Right now, weather forecasters are not getting too specific with the extended forecast as the models are in disagreement with their solutions. Stay tuned! Parts of the West Coast are finally getting some desperately needed rainfall (with snow in the higher elevations). It’s not going to put much of a dent in the extreme drought but any moisture is welcome. Once winter is over, the chances of precipitation drop off in California so they only have several weeks left to catch up. The northern part of the state has the best chance of seeing any precipitation. Maybe there will be an El Nino next winter which would normally bring more precipitation to California. That is a possibility. That’s it for now. Have a great weekend!

THE WEATHER PATTERN STAYS ACTIVE BUT WE SHOULD SEE RAIN AT VARIOUS TIMES THIS WEEK INSTEAD OF SNOW

The pattern this upcoming week will feature multiple chances of precipitation but due to a shift in the pattern, it should be in the liquid variety and not the frozen. The first opportunity for Hampton Roads to receive rain is on Monday. There will be another chance during mid-week and yet another next weekend. While cold air intrusions will still be occurring in the United States, they will not penetrate this far south with the intensity of the past few weeks. If you are traveling, there will be plenty of winter weather issues to our north and west so make sure you monitor forecasts this week. As a result of the changes in the upper-level winds, the parched state of California may finally receive some much needed wet weather, but not nearly enough moisture to put a dent in the extreme drought conditions there… The NFL gambled on the weather in Northern NJ today and it looks like they got lucky. Neither extreme cold nor snow will impact the Super Bowl…. Since we are now in early February, our average temperature has begun its rise which will reach its maximum in the month of July. We still have a lot of winter to go so don’t put away your sweaters and scarfs just yet!
