As if it isn’t already cold enough along the Gulf Coast, models remain in agreement on bringing some of the coldest air we have seen is over a decade or possibly two decades?
Arctic air is already positioned itself across much of the United States. This is in response to a large vortex sitting over the Great Lakes/Northeastern region. This vortex is funneling Arctic Air from the poles straight into the Central/Eastern US. A reinforcing shot of colder air will come through at the beginning of the work week lowering temperatures even further. Here is a look at the numbers to start the week…
Monday- Mostly Sunny and Breezy. COLD! Highs around 46. Lows around 32
Tuesday- Mostly Sunny and Cold. Highs around 47. Lows around 30.
Wednesday- Filtered Sunshine and Cold. Highs around 49. Lows around 32.
Beyond Wednesday things become very interesting. A strong high pressure will build in Canada and start to head south underneath a digging upper-level trough. This high pressure will be very strong 1050MB+ and bring with it frigid temperatures. At the same time a surface low will develop in the Gulf on Thursday just as the Arctic front is moving through. This will mean snow/ice/sleet for many locations in the Deep South; however, we will have to iron out those details as we get closer. Either way, the air coming for Thursday thru Sunday could be the coldest air our area has seen since 1989.
We most certainly will be in hard freeze warning criteria and also could see some wind chill advisories. Everyone is advised to prepare their homes for pipe busting weather and also make sure all heating utilities are in good working condition.
More details to come…
