Wednesday’s wind will rattle trees, then lack of breeze leads to frost/freeze; Thursday’s high pressure brings nicer weather
Over the past few days, we’ve had some fun weather to talk about. We got off to a rocky start with a strong cold front, suffered through wedge weather and survived the first reported snowflakes of the season for West Virginia! I leave you today with one more cold front, then pleasant autumn weather for Thursday. For those anxiously awaiting Kevin’s return, he will be back at the blog tomorrow!Waking up this morning to clearing skies and sunshine was a welcome sight after the last couple of days stuck under clouds and drizzle. The sun was almost blinding in some spots but also served to highlight any lingering valley fog in the lower valleys. Overnight, the stubborn wedge finally eroded as southwesterly winds brought in milder air.
The first part of the day will be calm with temperatures in the 60s to 70s in the Piedmont, but expect the winds to pick up as a cold front approaches from the west. The passage of the cold front this afternoon will be dry but accompanied by gusty winds due to a steep pressure gradient (change in pressure over a short distance). High pressure moves in directly behind the cold front, which should quickly calm the winds overnight.
Due to the high pressure, skies will clear and winds will decrease setting up the potential for some radiational cooling. For this reason, the Blacksburg National Weather Service has posted frost advisories and freeze warnings until 9 a.m. Thursday for counties west of Roanoke. They don’t expect the frost to be widespread, but cover or take in any outdoor plants just in case. Temperatures for tomorrow at 5 a.m. per the GFS model show temperatures right around freezing for much of the area, with some spots dipping into the upper 20s; the darker blues indicate the coldest temperatures. Expect a cold Thursday morning, followed by a nice day with temperatures in the 60s and 70s.
For some added discussion, Kevin asked that I post an article he wrote last week regarding The Weather Channel naming winter storms. My two cents? While the idea has some merit for increasing public awareness (much like names give tropical systems identity), the fact that other organizations such as the National Weather Service and local TV have not agreed and may not use the names will only serve to increase confusion for public awareness. Would love to hear your thoughts!
Thank you again to Kevin Myatt and The Roanoke Times for the opportunity to cover the Weather Journal blog over the last week. I have immensely enjoyed conversing with all you weather folk, and I hope we can continue to converse both in this forum and over Twitter (@KathrynProciv).
