We've got another challenging forecast to talk about this afternoon and this time it involves the possibility of ice.
The sky has been very cloudy today but radar continues to show no rainfall activity in the area. A few showers will be possible tonight as another cold front drops into the state. The greatest chance for a passing shower will be in northern communities. Temperatures tonight will remain above freezing so ice won't be an issue tomorrow morning. It will be colder tomorrow, with highs in the 40s. You can expect more clouds, with a small chance for rain.
Thursday night is when things get interesting as a cold air damming situation develops over Georgia. Cold-dense air associated with high pressure over the Ohio Valley Region will be flowing down the eastern Appalachian range and into Alabama tomorrow night. During this time we expect showers to develop as moisture overruns Alabama tomorrow night and on Friday. Temperatures will be very close to freezing and since the air will be dry, evaporative cooling could further lower the temp. So the chance for winter weather is back on the table.
So what type of winter weather, when and where?
A deep melting layer in the atmosphere will promote the development of freezing rain or glaze. The greatest chance for freezing rain will be from Blount County southeast to Randolph County and points east (we will have a map posted on our weather blog at http://www.myfoxtracker.com).
Up to 1/10 inch of ice accumulation will be possible in these areas and this could cause travel trouble. The primary concern will be Thursday night and Friday morning. For areas not in the winter weather threat, we expect cold and overcast conditions, with light showers. That said if you live in central and western Alabama I encourage you to check in for the latest forecast updates. Any small change in forecast temperatures could make a huge change in the type of precipitation see you at 5 p.m. and later tonight.
