THE COMBINATION OF A LOW PRESSURE SYSTEM IN THE GULF STATES AND HIGH PRESSURE OVER THE CANADIAN MARITIMES WILL BRING CLOUDS AND A COOL BREEZE TO HAMPTON ROADS

Don’t expect to see much sunshine or warm temperatures over the next couple of days. As the headline states, a low pressure system in the Gulf States will produce lots of clouds and the pressure gradient between this system and a slowly departing high pressure system over the Canadian Martimes will cause a cool northeasterly wind the next few days. Temperatures will be much below normal today (Friday). The difficulty in the forecast for meteorologists is to determine whether rain will make it this far north. Some computer models do have rain overspreading southeast Virginia early Saturday morning while other models do not and keep it confined to northeast NC. Either way, Saturday should be on the cloudy side with below normal temperatures again. Some heavy rain is expected in portions of the Southeastern States from this system. A slow warming trend is expected early next week… The frontal system that moved through earlier this week brought about 1.50 inches of rainfall to my neighborhood. I was up in the Wilkes-barre, PA area on Tuesday when the front moved through and that area received heavy rain. Snow fell Tuesday evening up there accumulating about an inch on grassy surfaces, roofs, vehicles, etc.

NICE WEATHER SHOULD LAST THROUGH MONDAY… A SLOW MOVING COLD FRONT IS EXPECTED TO BRING US SHOWERS ON TUESDAY

Today (Friday) will be warmer than yesterday as a southwesterly flow takes over. Due to the low relative humidity and the rather breezy conditions, the National Weather Service has issued an advisory regarding an increased fire danger today. So, please be mindful of that, especially during the afternoon and evening when winds are normally the strongest.  A weakening cold front is not expected to bring any significant precipitation to the Hampton Roads area on Saturday, but an isolated shower or sprinkle cannot be ruled out, especially in our northernmost areas. Saturday is expected to be a little cooler than today. We should stay dry though Monday but an approaching cold front is expected to bring us showers and possibly a thunderstorm on Tuesday. The exact timing of the rain is not certain right now. Much cooler weather is expected to follow the frontal passage during the middle part of next week. That’s it for now. Have a great day!

CLOUDS DOMINATE THE SKIES AS A FRONTAL SYSTEM SLOWLY MOVES OFFSHORE… BY THURSDAY, WE SHOULD SEE MOSTLY SUNNY SKIES WITH SEASONAL TEMPERATURES

A huge dip in the jet stream (upper-level trough) to our west is producing a moist southwesterly flow aloft. This, combined with disturbances in the flow, will maintain a chance of showers and should keep us mostly cloudy today (Tuesday). However, rainfall will not be as widespread as it was on Monday. About a half inch of rain fell in my neighborhood on Monday. Severe weather including a tornado was reported in parts of North Carolina on Monday causing injuries and property damage. The frontal system will be moving out to sea but a weak disturbance may yet again bring a shower or two on Wednesday along with some clouds. On Thursday, we should totally dry out making for a very pleasant day. That’s it for now. Have a great day.

THE WEEKEND WILL BE NICE AS HIGH PRESSURE BUILDS INTO THE MID-ATLANTIC STATES FROM THE NORTHWEST… RAIN CHANCES GO UP ON MONDAY AS A LOW PRESSURE SYSTEM APPROACHES FROM THE SOUTHWEST

After a rather warm day on Friday, high pressure will be building into the region today (Saturday) bringing dry and sunny weather. Temperatures will be cooler today and they should be even lower tomorrow as our winds switch around initially from the northwest but will become northeast by Sunday. At this time of year, a northeasterly wind is usually a chilly wind as the water temperature is still cold. This past week, we saw a wide range in temperatures across the region due to the predominately onshore flow.  Temperatures inland were near 80 degrees during some of the afternoons but near the coast, temperatures were much lower due to the wind off the water. The high pressure system that will bring us the great weather this weekend will move offshore on Sunday night giving way to an approaching low pressure area from the southwest. Rain chances will go up on Monday as the frontal system moves through the region.  By the middle of next week, we should dry out. Temperatures should be near seasonal levels.

FINALLY, WE SHOULD SEE SEVERAL NICE DAYS IN A ROW… THERE MAY BE SOME WET WEATHER AS WE HEAD TOWARDS THE WEEKEND

You know that spring is really here when weather forecasters say that temperatures will be cooler near the water. And that is what they are saying today (Tuesday, April 1st). A light northeast wind will make it cooler near the water as inland temperatures should reach into the 60’s. The bay and ocean take a long time to warm up during the spring season, so when the wind is blowing from a body of water, it will be cooler near those coastal areas… The low pressure system that brought the rain over the weekend and the windy conditions on Monday is now far out to sea. A cold front now moving through the Midwest should move through our region overnight tonight without any significant precipitation. The front will then return as a warm front but again, no major weather issues are expected. We will just see changes in wind direction and there will be some clouds at times. Later in the week, another cold front should approach and there might be some showers with that system. However, there is some uncertainty with the forecast for Friday and beyond so I’ll have an update later in the week on the weekend forecast… It’s nice to see the grass starting to grow again as the landscape is turning green. Of course, allergy sufferers know what this means… that pollen season cannot be far behind. That’s it for now. Have a great day!
