A weekend cold front will usher in chilly, Canadian air by the end of the weekend. It's one of the stronger fronts we've seen so far this fall.
CANADIAN AIR COMETH
Currently (Thursday), the cold front stretches through the Dakotas with temperatures only in the 30s and 40s with snow falling behind the front in Montana. While not unheard of, it is a bit early for this type of snowy weather there. National Weather Service records there show the average first snow in Montana is in mid to late October.
We're not looking at anything like that, but you will notice sweatshirt weather by the end of the weekend and first of next week as highs plummet to the upper 50s and low 60s. You read it right. Highs.
Here's a look at the forecast temperature change for a few or our hometowns NOTE: This is the forecast as of Thu, Oct 4)
ROANOKE: Sat: 76 Sun: 58
LYNCHBURG: Sat: 77 Sun: 58
DANVILLE: Sat: 85 Sun: 70
BLACKSBURG: Sat: 74 Sun: 58
HOT SPRINGS: Sat: 66 Sun: 53
Sunday and Monday will be the cool days, with temperatures moderating through next week.
While the cool snap won't be off the chart, it will offer weather typically reserved for late October and early November.
Average highs for the start of the October are typically around 74. By the end of the month, the average high drops to around 63 degrees.
END TO THE GROWING SEASON?
Some hometowns have already seen their share of frosty conditions during the first few weeks of autumn. Sunday and Monday offer another opportunity.
Locations from the Midwest to the Appalachians, where nighttime lows early next week are forecast to dip into the 30s. Sunday night and Monday night will be the coolest. Keep in mind, your thermometer is typically eye level. Since cooler air sinks to the surface, the ground may actually be cold enough for frost to form.
FIRST MOUNTAIN SNOWFLAKES
There is a chance that wet snowflakes will mix in Sunday afternoon over the higher mountains in parts of West Virginia, western Maryland, northwestern Virginia. We're not talking big snow. Rather, a few snowflakes as the cold air comes in.
The temperature trend keeps highs mainly in the mid/upper 60s Wednesday through next weekend, with minor ups and downs following that. The 6 to 10 day outlook highlights below average temperatures will likely stick around through at least the middle of the month.
