The Next 24 Hours – A Little Snow and a Cold Rain on Friday

PSNOW_2inch

It’s “snow” big deal at all with this talk of wintry mix overnight through Friday morning. There are no advisories, and no significant accumulation of snow or ice is expected. A few flakes are possible amongst the raindrops, but even then, it will be spotty.

Here’s the chance of getting snow accumulation of an inch or more. Think of it this way, if I told you there was a 10% chance of rain on a summer day, would you worry much about getting wet? This is the same kind of map; just the chance of a different type of weather:

The chance of a few snowflakes overnight into Friday morning brings out a lot of questions. How rare is this kind of weather this late in March? Here are some answers from UAHuntsville’s and Alabama’s State Climatologist Dr. John Christy:

“It’s rare, but it has happened before,” said state climatologist John
Christy at The University of Alabama in Huntsville (UAH). “We did a partial
review of data from stations across the northern half of Alabama and found
that many of those stations have seen four or five snow events on or after
March 22 over the past 100 plus years.”

There was, of course, the spring storm of April 3, 1987, which dumped heavy
snow across a swath of central Alabama, including five to six inches
around Birmingham, two inches in Cullman, almost three inches in Anniston,
four inches in Talladega, two inches in Haleyville and 10 inches of snow in
Valley Head. In April.

Valley Head has seen snow as late as April 7, 1971, when it got almost two
inches of snow.

Huntsville got about four tenths of an inch of snow on March 25, 1940. That
was a cold winter and spring: The Tennessee River froze over.

Florence has gotten snow as late as March 28, but that was in 1894 when the
city saw about one inch of snow.

Temperatures will run about 20 degrees below average on Friday afternoon! Expect a high in the mid-40s with a good chance of scattered showers. Rain will be heavy enough to drop about a tenth to a quarter-inch of rain Valley-wide on Friday and Friday evening. Some communities south of The Shoals in Franklin, Marion, Winston, Cullman, and even parts of Lawrence and Morgan Counties could see up to a half-inch of rain through Friday night.

More rain is on the way for the weekend, but there is good news on Saturday – a break in the showers may come just in time for a lot of midday activities like the Eggstravaganza at Ingalls Harbor Pavilion in Decatur.
