Thanksgiving is here and whether you hit the road or took to the skies, hopefully you made it to your destination with a minimum of headaches. Airlines have reported minimal delays and cancellations due to the relatively calm weather so far this week.
Unfortunately, that could change in the coming days as a more active weather pattern takes shape over the eastern US.
But first, some good news. The weather is looking great for the Macy’s Thanksgiving Day Parade. The sky is mostly sunny and most importantly the wind will be light so there should be no restriction on the balloons.
Active weather is underway across the southern plains on Thanksgiving Day.
The Weather Prediction Center said, “The main area of concern into the Thanksgiving holiday will be the potential for a dynamic low pressure system to affect portions of the Southern Plains and lower Mississippi Valley with heavy rain, snow and thunderstorms.”
Rain and thunderstorms are expected in all cities, including Dallas, Houston, New Orleans, Memphis, Tennessee, Shreveport, Louisiana, and Little Rock, Arkansas, as we approach, affecting any outdoor cooking plans during the day. Can
While the timing of the rains may not be the best, about 70% of the south is in drought conditions, so rains will be beneficial. Widespread totals of 1 to 2 inches are expected with isolated higher amounts from East Texas to Mississippi.
Showers of rain will spread to the Ohio Valley and Great Lakes Thursday afternoon and Thursday night with a cold front moving north. These rains will be more scattered and very light over the lower Mississippi Valley.
Heavy rain from the Mississippi Valley extends into the Deep South on Thursday night and Friday morning while light rain across the Ohio Valley extends into the Northeast. Most of this rain will be pushed offshore by mid-afternoon Friday.
While the western US will experience cool weather for Thanksgiving Day, Southern California is expecting another Santa Ana event that will bring a high fire to the Ventura Valley to the Los Angeles area, especially the San Gabriel Mountains. Wind gusts are expected to exceed 40 mph and may even reach 60 mph in some higher areas. These winds combined with low relative humidity will create unfavorable fire conditions.
As rain moves east, lower upper levels will cause temperatures to cool enough for snow over parts of West Texas.
“There should be enough cold air in the upper lows over the southern High Plains to produce effective snow accumulation over parts of eastern New Mexico and far west Texas beginning Thanksgiving night through Friday,” the Weather Prediction Center said. “Snow accumulations of 3 to 8 inches are possible, with locally higher amounts especially in higher terrain, with the potential for hazardous travel conditions.”
“There is still some uncertainty regarding the timing and location of the heaviest snow bands associated with this system, but those holiday shopping or traveling within the Texas panhandle should be prepared for impacts from snow Thursday night-Friday morning.” should be considered,” the Weather Prediction Center said.
“We have the potential for banding of snow where there can be little or no snow in one area, and several inches of snow in another area a short distance away,” said the National Weather Service in Amarillo.
Farther east, it will rain throughout Friday in central Texas. Rain will spread over eastern Texas and the lower Mississippi Valley late Friday and Saturday as the snow abates. Another widespread 1 to 2 inches is expected, bringing some locations up to 4 inches between Thursday and Saturday.
Rain will push east again into the Ohio Valley and Deep South on Saturday night.
Rain will continue to move eastward throughout Sunday, affecting much of the Eastern Seaboard from northern Florida to New England.
It is expected to delay travel in several major hubs from Chicago, Detroit and Charlotte to New York, Philadelphia and Washington in the afternoon.
While rain is expected to delay travel to the east coast, very little snow is expected to fall this time.
“The good news is that temperatures should be warm enough that nearly all precipitation will fall as rain over the US, but the bad news is that rain and strong winds will lead to wet roads and potentially long airport delays for major centers on Sunday.” The delay will make up for the Northeast,” said CNN meteorologist Dave Heinen.
