Colder air returns Thursday and continues through the weekend

After 15 straight days of above average temperatures, a more seasonal chill settles in to the Tennessee Valley starting Thursday. Below average temperatures should continue into the weekend.

FINALLY FEELING MORE LIKE JANUARY

Wednesday was the 15th straight day of above average temperatures. So far, the average temperature for January 2017 in Chattanooga is 50.3 degrees. This is a whopping 10.2 degrees above average for January. However, it is not the record warmest. The current record holder is January of 1950 with an average temperature of 53.7 degrees. That record seems safe as our local temperatures for the last few days of the month should be below average for a change. Last January was below average with the average temperature of 38.6 degrees.

Seasonably cold air should move in during the day Thursday. Breezy at times, but drier with temperatures during the afternoon holding in the upper 40s. A breeze from the west at 10-15mph will make it feel even colder at times. Temperatures for Thursday Night and Friday Morning should drop to the freezing mark. A few flurries or patchy areas of light snow could occur over the far northern and eastern part of the viewing area overnight Thursday Night. Sunny to partly sunny Friday, but high temperatures holding in the low to mid 40s. The average high and low for late January is 51/31.

WEEKEND CHILL

The colder than average trend should continue through the weekend. Sunny to partly sunny Saturday with morning lows in the upper 20s and afternoon highs in the mid 40s. Highs on Sunday should again be in the low/mid 40s after a morning low in the upper 20s.

Besides the temperatures we will also be keeping an eye on the northwesterly upper flow that could bring a weak disturbance through the viewing area Sunday and Sunday Night. As mentioned in our earlier post, moisture amounts look very light with this system. This is not the type of system that brings a lot of snowfall. But, this could bring a dusting and/or light accumulation late day Sunday and Sunday Night. The main concern being some slippery roads as temperatures drop below freezing for Monday Morning. The remainder of Monday looks chilly, but above freezing in the mid 40s by afternoon.

We'll keep you updated if anything changes with the weekend weather pattern!

SEASONAL NEXT WEEK

Temperatures should remain below average Monday, but gradually rise above seasonal levels through Tuesday and Wednesday. Mainly dry with afternoon highs in the low 50s Tuesday and possibly mid/upper 50s Wednesday. Temperatures should be below freezing Monday Morning, then average in the mid 30s Tuesday and Wednesday Morning.

As always, you can depend on the StormTrack 9 Team for updates!
