A HISTORIC EARLY SEASON SNOWSTORM POUNDS PARTS OF THE NORTHEAST… TREES AND LIMBS WITH LEAVES ON THEM SNAP DUE TO THE WEIGHT OF THE HEAVY, WET SNOW… WHILE THE WEATHER IMPROVES, ANOTHER LOW COMING UP FROM THE SOUTH MAY BRING SOME WET WEATHER LATER MONDAY TO HAMPTON ROADS

It was truly a remarkable storm for late October. Heavy snowfall blanketed a large area of the Northeast causing power outages, travel disruptions, etc, etc. This pre-Halloween snowstorm will go down the the record books as one of the earliest winter storms to ever affect the region. The cause was a low pressure system that intensified as it moved up the East Coast feeding on the warm waters of the North Atlantic and being in between two very different air masses. What made this a very serious situation is that in many areas of the Northeast, the trees still had their leaves on them. This adds to the overall weight of the snow on the branches.  I was up in Charlottesville, VA on Saturday and snow fell there as well although it melted as the snow turned to a very chilly rain. Snow mixed in as the precipitation ended. When I awoke Saturday morning, the vehicles had snow on them. Here in Hampton Roads, light rain fell and I picked up about a half inch of rain. The storm system is right now off the New England coast and is quite a strong system as it pulls away…. Our Sunday looks like it will be a sunny day but there will be an unseasonable chill in the air. Then, another low pressure system will develop well to our south and west and it will move off the coast on Monday night and Tuesday. This system may bring a period of rain to the Eastern VA Monday night and early Tuesday. No snow is expected with this storm. Sunshine should return on Wednesday. There are no areas of concern in the tropical Atlantic at this time.

AFTER SEVERAL NEARLY PERFECT WEEKENDS IN A ROW, THIS WEEKEND WILL START OUT WET BUT WE SHOULD HAVE A DECENT SUNDAY… TEMPERATURES TAKE A NOSEDIVE… SNOW IS LIKELY IN THE MOUNTAINS OF WESTERN VIRGINIA AND IT WILL EXTEND INTO THE NORTHEASTERN STATES

The last few weekends have been sunny and pleasant but our luck has run out. A cold front moved through Hampton Roads overnight ushering in much cooler weather. The front will eventually stall to our south. In the meantime, upper-level energy will be helping to develop a low pressure system to our south and west. This low will move east-northeastward towards North Carolina. This will cause overrunning precipitation to develop across VA spreading from west to east Friday into Saturday. Rain should overspread Hampton Roads Friday night and will last through part of Saturday. In addition, winds will increase as the low approaches. The rain may fall moderate to heavy in some areas. Farther to the north and west, snow may mix in with the rain at times. The highest elevations of VA may receive accumulating snow. The storm system will eventually become a nor’easter as it heads up the coast. Significant snow amounts may occur in parts of the Northeast on Saturday. And it’s not even Halloween yet! The low will move away Saturday night and Sunday so we should have a fairly nice day on Sunday, albeit on the cool side… Tropical Storm Rina is expected to drift around near the Yucatan Peninsula for the next few days. That’s it for now. Have a great day.

ANOTHER DRY WEEKEND IS IN STORE FOR HAMPTON ROADS… RAIN CHANCES STAY LOW UNTIL NEXT THURSDAY… WE’LL SEE A SLOW WARMING TREND THIS UPCOMING WEEK… WILL WE SEE A NEW TROPICAL STORM IN THE ATLANTIC BASIN?

Well, the weekend is here again and the weather should be great for most outdoor activities. Although high pressure will be nearby, clouds will be around especially on Saturday but no precipitation is expected at this time. The next chance of rain will probably be on Thursday or Friday when a cold front and the associated trough approach the region. Prior to that, temperatures will warm up a bit by mid-week. This past week’s system brought about 1.40 inches of rain to my neighborhood. Norfolk also saw a record high temperature earlier in the week of 86 degrees. There is an area in the Southwestern Caribbean Sea that is being monitored by the National Hurricane Center (NHC). Right now, according to the NHC, there is a 70% chance of development. That’s if for now. Have a great day and thanks for reading.

AFTER A FANTASTIC WEEKEND, WARMER WEATHER IS ON THE WAY WHICH WILL BE FOLLOWED BY SOME WET WEATHER BY MID-WEEK… WE DRY OUT AND COOL DOWN LATER IN THE WEEK… THE NATIONAL HURRICANE CENTER IS CLOSELY WATCHING AN AREA NEAR THE YUCATAN PENINSULA

Sunday’s weather will be similar to Saturday but there will be less wind. The large low pressure system in Canada has moved further north and east and now we are no longer within it’s large cyclonic flow. Warmer air is going to move into Hampton Roads on Monday causing temperatures to rise to around 80 degrees. Tuesday will be another warm day but conditions will begin to change as a cold front and low pressure area approach from the west and southwest. This could be a potent system as there will be plenty of moisture around to produce high rainfall rates. Severe weather may be possible, too. It will be interesting to see if moisture from what is now a tropical disturbance near the Yucatan Peninsula could get entrained into this system. If that happens, we could get a real soaking. That system’s development  is being hindered by land but it may become the next tropical cyclone over the next couple of days. This morning, it looks quite impressive on satellite imagery. Don’t forget that we still have about six weeks left of hurricane season to go as the season ends November 30th. Normally, tropical cyclones that develop in October are in the Caribbean Sea and we no longer see the long-tracked cyclones that track westward across the Atlantic Ocean. These long-tracked systems are referred to as Cape Verde storms. Either way, once the storm system leaves later in the week, we will dry out and cool air will follow possibly making for another very pleasant weekend next week.

ANOTHER GREAT WEEKEND IS IN STORE FOR HAMPTON ROADS… A WARMING TREND IS EXPECTED EARLY NEXT WEEK WHICH WILL BE FOLLOWED BY COOLER WEATHER LATER IN THE WEEK

The weather this weekend will be nearly perfect for the middle of October. Winds will be a bit brisk on Saturday due to the pressure gradient around a low pressure system just north of the Great Lakes. The winds will lessen on Sunday as the low moves away. Humidity levels have come down which will make it feel quite comfortable in the afternoons both days of the weekend. Temperatures are expected to trend upwards early next week ahead of a strong cold front that will be approaching from the west. Some showers and possibly thunderstorms are expected with this frontal passage which should be during the mid-week period. Temperatures behind that front will be much cooler… The total rainfall this past week in my backyard was around a quarter of an inch. Most of this rain fell on Thursday. That was the day that the two tornadoes touched down in New Kent and Louisa Counties in Virginia. That part of Virginia had a 5.8 magnitude earthquake and a hurricane in August, and now a tornado. Unreal!… The tropical Atlantic is quiet but there are two areas of concern. One is just east of the Yucatan Peninsula and the other is out in the Eastern Atlantic. That’s it for now. I’ll have an update on Sunday.
