AS HIGH PRESSURE SETTLES INTO THE REGION, OUR WINDS HAVE SLACKENED OFF MAKING SUNDAY A CHILLY BUT SUNNY DAY… TEMPERATURES WARM BACK UP THIS COMING WEEK WITH RAIN CHANCES INCREASING BY MID-WEEK

Saturday’s strong winds were the result of a strong low pressure system over Southeastern Canada. I was travelling up to NJ on Saturday and it was even windier up there with snow flurries occurring every once in a while. As the low pulls away, our winds have slackened off making Sunday a rather nice, but chilly day. This will probably be the coldest day of the week as a warming trend will set in on Monday. There seems to be two chances of rain this week, one during the mid-week period and the other next weekend… Meteorological Winter will soon be ending and we will see our average temperatures start to rise more steadily. The Mid-Atlantic states really dodged the bullet this winter with very few winter storm threats. As I mentioned in previous posts, this was mostly due to a lack of a blocking pattern which seems to be continuing.

FRIDAY WILL BE A WARM AND WINDY DAY WITH A POSSIBILITY OF SHOWERS/STORMS… THE WEEKEND WILL BE MUCH COOLER

A strong cold front will be moving through the Mid-Atlantic States Friday night but ahead of the front, a surge of very warm air will bring unseasonable temperatures to Hampton Roads. The front might be preceded and accompanied by showers and thunderstorms, some of which could be severe. Winds will be very gusty ahead and behind the cold front. The weekend will be much colder as a cold high pressure settles into the region behind the intensifying low pressure system that will be moving away to the northeast. High temperatures on Friday should be around 80 and high temperatures on Sunday may not get to 50. I’ll have an update on the extended forecast on Sunday.

THE LOW PRESSURE THAT BROUGHT MOSTLY RAIN TO HAMPTON ROADS MOVES OUT TO SEA… A WARMING TREND SETS IN THIS WEEK

The storm system that brought mostly rain to Hampton Roads is moving away and in its wake, we will see slowly improving conditions. The northerly winds that have been quite gusty overnight will be diminishing today and we should see some sunshine later on. About 1.5 inches of rain fell in my Virginia Beach backyard. The South-side didn’t have any accumulating snow. However, some minor snow accumulation was reported just to our north and west. Central Va received more significant snowfall… After a chilly day on Monday, the weather this week will almost be springlike with temperatures expected to be in the 60’s Wednesday and Thursday. A couple of weak systems may bring us showers later in the week.  Thanks for reading and have a great day.

SUNDAY WILL TURN WET AND WINDY AS A LOW PRESSURE SYSTEM SLIDES TO OUR SOUTH AND INTENSIFIES… SOME SNOW MAY OCCUR AS THE SYSTEM PULLS AWAY, BUT SNOW ACCUMULATIONS, IF ANY, SHOULD BE MINOR HERE IN HAMPTON ROADS

The forecast from yesterday seems right on track with rain getting ready to spread into Hampton Roads. It will be light and intermittent at first but it should pick up as the day progresses. Winds will also pick up as the pressure gradient increases. Coastal areas will see waves increasing but tides should only be slightly above normal. The rain may turn to snow as the low begins to pull away off the coast. Exactly how much snow we receive is questionable now as it is not certain how long the snow will last after the changeover. Also, temperatures will be marginally cold enough for snow, so the other factor is whether the snow will stick. Right now, the forecast is an inch of snow or less for Hampton Roads. However, as you go north and west, accumulations increase. For example, Richmond is expected to receive one to three inches of snow. On Monday, it’s over and temperatures should rise to the mid to upper 40’s. It appears that a warming trend will set in by mid-week. A couple of weak systems may affect the area later in the week. I’ll have an update on Monday. Thanks for reading and have a great day.

A DEVELOPING LOW PRESSURE SYSTEM OVER THE WESTERN GULF OF MEXICO IS POISED TO GIVE HAMPTON ROADS A SOAKING RAIN ON SUNDAY WITH SOME SNOW POSSIBLE AS THE SYSTEM DEPARTS

If you need to do anything outdoors this weekend, try to get it done on Saturday as Sunday looks to be a wet day. A developing low pressure system near the Western Gulf of Mexico will be tracking E-NE which should take the system off the Southeast Coast Sunday night. This should spread rain into our region on Sunday and snow will fall in areas to our north and west. Parts of Western and Central Virginia may see significant snowfall, but not a paralyzing snowstorm. Even the Eastern Shore may get in on the action Sunday night, but only a couple of inches are expected at most. In Hampton Roads, this will be mostly a rain event… Speaking of rain, about 0.60 inches fell in my backyard from a system that moved through on Thursday…. Due to the continued lack of blocking, this system will not become a major nor’easter for New England. The low is expected to move out to sea and not affect areas of the Northeast. When an upper-level high pressure system is near Greenland, this causes blocking as we saw last winter. The blocking causes low pressures like the one coming out of the Gulf to crawl up the East Coast and blast the I-95 corridor with heavy snow and strong winds. So far this winter season, this really has not happened. We haven’t seen much blocking at all.  And time is running out. I’ll have the weather picture for next week in my Sunday morning post.
