Pinpoint Weather: Rain ending and the cold air arrives for the weekend across Virginia
Heavy rain fell early Friday morning in our Piedmont counties as several cities received over a quarter of an inch of rain before 10 am.
Chase City 0.58
South Boston 0.27
This was the first wave of rain that will mover over Virginia today, the second is associated with a cold front that will migrate across the region later in the day or early evening. Rainfall with that line is much less and the area should only see around a tenth of an inch.
The bigger result from the front will be the much cooler air today and more specifically tonight. A blast of cold air will drop the mercury down into the upper 20s in some mountain locations and into the mid to upper 30s over areas east of the Foothills. Clear skies will aid in the temperature drop and the National Weather Service has issued a Freeze Warning for our western counties tonight and a Frost Advisory for the Foothills. The Frost Advisory may be upgraded later and I will watch that for you.
The growing season in the Highlands and NRV is scheduled to end on October 25th, but if a county gets a hard freeze over more than half the county, it will officially end the growing season for that county. Basically, the growing season is coming to and end shortly, but a hard freeze tonight may accelerate that time line.
Saturday looks to be a crisp and cool fall day as the ground soaks in the rain from Friday and we dry out. The temps will be in the middle to upper 50s in the mountains and the low 60s east of Interstate 81 for highs and the time to break out the sweaters is at hand. Look for the cool pattern to return on Sunday as we will drop into the 30s overnight Saturday into Sunday and have a tough time recovering to normal. The flow of air will be from the northeast so a weak wedge pattern, or cold air damming, will set up east of the Foothills. A mix of clouds and sunshine can be expected.
Monday will see a bit more clouds late in the day ahead of what should be a weak rain maker for late Monday and Tuesday. The chance for rain is expected to be in western counties and may not make it past the spine of the Appalachian Range. Temperatures next week will be in the middle to upper 60s to low 70s each day.
