The next few days will be rain-free and particularly chilly from tonight through Friday morning.
We currently have a series of high pressures set up to our west, as shown below.
High pressures have a clockwise circulation around them, so since they are to our west, these high pressures are causing for our winds to be from the North and thus bringing in cooler air.
By dinnertime, a cold front moving from the west will be over-top of us, raring to bring below average temperatures for the rest of the week.
Lots of sun is expected the remainder of the week, but a cold Arctic airmass will keep afternoon temperatures way down.
Cloudy skies will prevail throughout the remainder of the day and into tonight.
One of our short term models has now decided that it wants to put some light showers over our area tomorrow.
Showers, if we see any, should be fairly scattered and brief. The AM work commute could be wet and you may need an umbrella heading into the office tomorrow morning. NAM 4 has the showers drifting around through the morning, but mostly gone by the lunch hour.
The next 48 hours will include much of the same, bitter cold that has invaded the central and eastern U.S.
Warm air begins to advect (propagate) into southern and middle Tennessee during the day on Sunday. The center of high pressure that was entrenched over-top of us keeping our temperatures down will slide east towards the Appalachians, and relatively warmer air will arrive to replace the chill.
The day has finally come that we have been talking about for quite some time now, our first dose of winter-like weather.
Keep in mind over the next couple of days, we will see some calm winds of about 5-10 mph. While this doesn’t seem like much, this wind will add in wind chill. Expect for it to feel even colder than those high temperatures (the wind chill isn’t forecast to go above 32° tomorrow and this is what it is going to feel like).
