By the end of this week, you won’t need this breathspray to feel Canadian.
Rest of Tonight – High 60, Low 42
This morning we picked up 0.11″ of rain officially at the airport.
Tonight, another cold front will be sweeping through. We may get a brief shower as the front arrives. Here’s the HRRR at 1 a.m.:
We’ll also get a reinforcing blast of cold air.
Check out these scary-cold phrases for the end of the week for middle Tennessee. This is from the NWS’s latest Hazardous Weather Outlook:
Wednesday – Cooler & Windy – Morning Low 39, Afternoon High 55
7a 43 . 10a 48 . 1p 53 . 4p 54 . 7p 50 . 10p 45
We’ll wake up in the 40s, but unlike the past few days, we won’t warm up much. Winds will be coming out of the NW at 10 – 15 mph (gusting even higher at times). Make sure to grab the jackets!
Hi-Res NAM model forecast temps (looping from Wednesday at 2 am to 8 pm) shows cold Canadian air diving in:
Thursday – Still Cold + Small Rain Chance – Morning Low 32, Afternoon High 57
7a 40 . 10a 48 . 1p 55 . 4p 56 . 7p 49 . 10p 41
Yet another cold front will push through, further reinforcing the cold air.
There is a very slight chance of a passing shower as the front passes. Pull out the winter clothes if you haven’t already. Even colder air is coming is weekend as we deal with another cold front.
Friday & Saturday – Very Cold
29 degree wind chills are forecast Friday morning. The temp is expected right at freezing, warming into the low 50s.
Saturday morning’s wake-up temp will be 30 (!) degrees. Light winds will shove wind chills into the upper 20s. Fortunately, temps will start to slowly warm back into reasonable levels. We should reach 56 by noon, on our way to a high of 61.
This early season cold is very unusual this time of year. These temps are more indicative of December. To illustrate this, here’s the GFS 2-Meter Temperature Anomaly for Saturday morning (translation: this is how much colder-than-average the GFS model thinks it will be Saturday morning). We’ll be 20 degrees below normal:
It seems our weather this year has been unusual. No real snow, not much (if any) Spring severe weather season, a cold snap in May, and a cooler/wetter-than-average Summer. We never even reached 100 this year.
