HIGH PRESSURE BRINGS SUNNY AND COLD WEATHER THIS CHRISTMAS DAY… TEMPERATURES MODERATE ON THURSDAY AND DRY CONDITIONS SHOULD PREVAIL

After the record breaking warmth this past weekend, temperatures have taken a plunge to below normal readings here in Hampton Roads. The frontal system brought a decent amount of rain to most of the area on Monday. There were several bands of very heavy rain that moved through parts of the region. I don’t think that we will have to worry about any wet weather for a while as we should stay dry for a few days. Although Christmas Day will be a chilly one, winds should be on the light side. Temperatures will quickly moderate on Thursday…. Have a Merry Christmas and stay safe!

WINTER BEGINS TODAY (SATURDAY) BUT IT SURE WON’T FEEL LIKE IT… RECORD BREAKING TEMPERATURES ARE POSSIBLE THIS WEEKEND IN MANY AREAS OF THE MID-ATLANTIC AND NORTHEASTERN STATES… HEAVY RAINFALL IS POSSIBLE ON MONDAY

The winter solstice occurs today, but the weather will not be winter-like at all here in Hampton Roads. A warm southwesterly flow may bring us record high temperatures. This is out ahead of a strong cold front in the center of the nation that will only slowly move eastward throughout the weekend. Severe weather is possible out to our south and west today as the front moves east. Behind this front, the air mass is much colder with snow and ice occurring in some areas. Rain and thunderstorms along and ahead of the front will affect us Sunday night and Monday. Rainfall amounts could be quite significant in some parts of our area. High temperatures should be in the 70’s both days this weekend and Sunday will probably the warmest day. As the front approaches the our area, it will slow down and that is why forecasters believe that we may see a lot of rain on Monday. A wave of low pressure may form, too, enhancing the rainfall. Then, temperatures return to normal and possibly below normal on Tuesday and Wednesday, but we will dry out… Getting back to the winter solstice, and what it means. The sun’s direct rays will reach the most southern point in the Southern Hemisphere, which is the Tropic of Capricorn around noon today (EST). It is the shortest day of the year in the Northern Hemisphere. Starting tomorrow, the days actually start getting longer, but the change day to day starts out very slowly and is barely noticeable at first.  The four seasons occur due to the earth’s tilt on its axis.

THIS WEEK WILL FEATURE SOME DAY TO DAY TEMPERATURE CHANGES BUT OVERALL IT SHOULD BE DRY THROUGH FRIDAY… RAIN CHANCES GO UP BY THE WEEKEND WITH MILDER TEMPERATURES EXPECTED

While there will be fronts moving through the Mid-Atlantic region this week, the only impact here in Hampton Roads should be just some clouds and day-to-day temperature changes. No extreme temperatures are expected and there shouldn’t be any major storm systems moving through the area. Places to our north may have a little snow as an Alberta Clipper moves through the Northeast. We did pick up a decent amount of rain on Saturday (over an inch) which made a dent in our precipitation deficit. However, we’re still below normal for the year. There may be some rain this coming weekend but it’s a bit too soon for any details. Temperatures should rise to above normal levels this weekend.

RAIN IS FORECAST TO DEVELOP LATER SATURDAY AND LAST THROUGH MOST OF SATURDAY NIGHT… MILDER AIR FROM THE SOUTHEAST MOVES IN AHEAD OF THE LOW PRESSURE SYSTEM… SKIES SHOULD SLOWLY CLEAR ON SUNDAY… MONDAY SHOULD BE NICE BUT A BIT ON THE CHILLY SIDE

A large low pressure system to our southwest will be transferring its energy to a new low pressure system that is expected to develop near the East Coast later today (Saturday). The new low pressure system will move northeastward up along the coast bringing a significant snowstorm to many areas of the Northeastern States. Mild air being drawn in out ahead of the low pressure system will boost temperatures here in Hampton Roads well into the 50’s, so frozen precipitation will not be an issue around our neck of the woods. Rain is likely to develop sometime this afternoon and it will continue well into the night. There may even be some heavy rain at times. The rain should end Sunday morning and conditions should improve later in the day as the low pulls away. Monday will be dry but temperatures will be on the chilly side. Most of the upcoming week should be dry with temperatures fairly seasonable for this time of year.

AFTER A VERY WARM FRIDAY, THE MUCH ADVERTISED COLD FRONT BRINGS US BACK TO REALITY… THE FRONT WILL STALL WITH WAVES OF LOW PRESSURE MOVING ALONG IT

Why couldn’t Friday’s beautiful weather last through at least one day of the weekend? Well, the frontal system that has been responsible for the brutal winter weather out to our west moved through overnight accompanied by periods of rain, some of it heavy. Temperatures probably won’t get out of the 40’s on Saturday, which is a major change from Friday’s temperatures in the upper 70’s. Overrunning moisture and waves of low pressure will result in periods of rain throughout the next few days. Areas to our west may see frozen precipitation on Sunday as colder air moves into that region. Another system will bring back precipitation into Virginia on Sunday after a break later today (Saturday). Snow and some ice accumulation is possible in Western and Northern sections of Virginia and there are Winter Storm Watches and advisories currently in effect for those areas. If you are traveling out that way, check with the NWS forecast or the local media forecasts for that those regions. For Hampton Roads, precipitation will only be in the liquid form. We should see a brief warm-up on Monday only to be followed by colder weather again. Rain chances should remain with us through Tuesday, but it will not rain all of the time. There may even be peaks of sun at times but honestly, weather forecasters in Virginia have their hands full this weekend, especially in the areas expecting wintry precipitation.
