THE WINDS WILL SLOWLY DIMINISH AS HIGH PRESSURE MOVES INTO THE MID-ATLANTIC STATES… AFTER A VERY COLD SATURDAY, MILDER AIR MOVES INTO THE REGION ON SUNDAY… A LOW PRESSURE SYSTEM IS EXPECTED TO BRING RAIN TO OUR REGION SUNDAY NIGHT AND EARLY MONDAY

The pressure gradient between high pressure to our west and a departing low pressure system to our northeast has been creating strong winds across Hampton Roads. As the high pressure area moves closer today (Saturday), the winds will diminish, but temperatures are expected to be much below normal despite abundant sunshine. A low pressure system will be organizing to our west on Sunday and it will spread cloudiness into our part of the country. The clouds will slowly lower and thicken and by Sunday night, we should see some rain move in. Luckily, (or unluckily if you are a snow lover), milder air will be moving into the region from the southwest. This will ensure that precipitation will be in the liquid form across Hampton Roads. The rain will end on Monday and temperatures are expected to drop later in the day. According to weather forecasters, there is only a very slight chance of a snow flurry as the precipitation ends on Monday, but odds are precipitation will end long before it is cold enough to produce snow here locally. Up north, it’s a totally different story, so if you are traveling up to states such as Ohio, Pennsylvania, or New York, you should check the forecasts up there as snow is expected. It probably won’t be a blizzard but significant snowfall is expected in some parts of the Mid-West and Northeast on Monday… Speaking of blizzards, you may have heard that a meteorologist in the Mount Holly, NJ National Weather Service office tweeted an apology to cities and towns in areas of PA, NJ, and NY that did not get the predicted blizzard earlier this week. There were basically two reasons that the heavy accumulations of snow missed areas such as Philadelphia, most of NJ, and NYC. The storm system was more compact than expected and it tracked a bit further east than models predicted. New England and Long Island received the brunt of the storm with heavy drifting snow measured in feet, strong winds, and tidal flooding. You probably saw the pictures of damaged homes along the coast of MA that were covered in ice… Now, back to our weather… On Tuesday, it will be very chilly again but it should be dry. Another system may affect us later in the week, but there is currently a lot of uncertainty with that system. That’s it for now. Thanks for reading and have a great weekend!

A BLIZZARD MAY IMPACT PARTS OF THE NORTHEASTERN STATES MONDAY NIGHT AND TUESDAY!

You’ve probably already heard that a major winter storm may impact the Northeastern part of the nation Monday night and Tuesday. Blizzard conditions are possible in areas from Central NJ through parts of New England and Long Island. The culprit is an Alberta Clipper low pressure system that will intensify very rapidly as it approaches the coastal waters. Please read my Weather Fact entitled “What does Bombogenesis Mean?” for an explanation as to what is expected to happen to the low pressure system. One of the big questions right now is how far southwest the accumulating snowfall will extend. Right now, weather forecasters are not predicting a major snow event for Hampton Roads. However, the Eastern Shore may get significant snowfall. Stay tuned as things can change! No problems are expected here locally through Monday evening. If there is going to be any accumulating snowfall, it will be Tuesday morning. Please monitor the local media and the National Weather Service for the latest updates.

THE WEATHER PATTERN OVER THE NEXT FEW DAYS WILL BE QUITE ACTIVE… A DEVELOPING LOW PRESSURE SYSTEM IS BRINGING WET WEATHER TO HAMPTON ROADS… THE SYSTEM INTENSIFIES AND MOVES AWAY ON SUNDAY BRINGING IMPROVING CONDITIONS… COLDER WEATHER IS LIKELY NEXT WEEK WITH A POSSIBILITY OF SNOW IN SOME AREAS

As the headline states, we are now in an active weather pattern which is very typical for this time of year. We’ll see day to day changes in the weather as a result of this active pattern. This morning (Saturday), there is an elongated area of low pressure just south and east of our region. This will consolidate into a rather strong low pressure system as it moves northeastward off of the New England Coast. While bringing rain to our region, the first major snowfall of the winter season is impacting parts of the Northeastern States today. Approximately three quarters of an inch of rain has fallen in my backyard so far but there is more to come today. The rain should become more scattered in nature later today. Sunday looks fairly decent for this time of year with predicted temperatures peaking around 50 degrees. Then, an Alberta Clipper system will be approaching the region on Monday which may bring us some rain, although we won’t see as much rainfall on Monday as we are getting today. As colder air moves into the region on Monday and Monday night, there is a possibility that we may see some snow or snow showers Monday night and early Tuesday as yet another system swings through our part of the country. Weather forecasters are not certain whether we will see accumulating snowfall here in Hampton Roads, but they seem to be indicating that there is a chance that we could see some minor accumulation in certain areas. I suggest that you monitor the local media and National Weather Service forecast as we get closer to this potential event. Either way, next week is shaping up to be a very chilly week. So, that’s it for now. Thanks for reading and enjoy your weekend!

AFTER A SUNNY AND CHILLY SATURDAY, RAIN IS LIKELY ON SUNDAY AND IT MAY BE HEAVY AT TIMES… MONDAY SHOULD BE DRY AND SEASONABLE

Wasn’t it great to see the sun yesterday (Friday)? After a stretch of damp and gloomy weather that lasted several days, we finally dried out on Friday. A little over 1.25 inches of rain fell in my backyard this past week. We’ll have another sunny day today, but it will be on the chilly side. A cold northeasterly wind is expected to slowly veer to a more southeasterly wind later today and tonight. That will bring in milder air for Sunday. A very moisture-laden system is expected to impact the Hampton Roads region on Sunday. Moisture from the North Atlantic’s Gulf Stream is expected to enhance the rainfall potentially resulting in heavy rain for parts of the region. Meteorologists expect about an inch of rain on Sunday if the forecast verifies. Rain should begin during the early morning hours on Sunday and it may become heavy during the late morning and early afternoon hours. Then, the rain will taper off later in the day. On Monday (Martin Luther King, Jr. Day), we should see a dry day along with seasonable temperatures as a cold front crosses the region. Speaking of seasonable temperatures, I wanted to point out that we are now approaching the coldest time of year on average for Hampton Roads. Beginning in early February, average temperatures begin to rise reaching their peak in July. I just thought I’d give you something to be hopeful about in the middle of January.. Have a great weekend and thanks for reading!

ANOTHER CHILLY AIR MASS MOVES INTO THE REGION ON SATURDAY… TEMPERATURES MODERATE ON SUNDAY… MONDAY IS LIKELY TO BE A RAINY DAY AND UNSETTLED WEATHER MAY LAST THROUGH MUCH OF THE WEEK

We saw temperatures moderate somewhat on Friday after Thursday’s brutally cold weather. However, breezy conditions on Friday made it feel chilly. A fresh shot of cold air moved into Hampton Roads Saturday morning and we may not see temperatures rise much above the freezing point today in some areas, despite ample sunshine. High pressure centered this morning near Kentucky will guarantee dry weather through most of our weekend. On Sunday, temperatures should return to near, or just below seasonal norms. A low pressure system is expected to take shape over the Tennessee Valley on Sunday and that should bring increasing cloudiness later Sunday. The combination of this low and a new secondary low that is expected to develop along the North Carolina Coast should bring us rain on Monday, beginning in the morning hours. There’s a possibility that we could receive a significant amount of rain on Monday. If you are travelling to the central and western parts of Virginia on Monday, you may run into freezing rain, so please be careful. The weather pattern may remain unsettled much of next week as a trough develops over the area along with additional disturbances bringing opportunities for precipitation later in the week…. Someone asked me why on some cold mornings, there is no frost on their vehicles while on other days, their vehicles are covered in thick frost. Wind speed plays a major role in frost development. When the winds are calm (or very light) and temperatures are cold enough, frost is likely. Clear skies also contribute to frost development. Note that air temperatures don’t have to be at or below freezing for frost development. The surface temperature of your vehicle may be much lower than the air temperature. Humidity levels also play a role.  The bottom line is that even though it may be very cold in the morning, strong winds will prevent frost from developing. That’s it for now. Have a great day!
