Yesterday, the RPM and NAM models had the low on Monday afternoon positioned about 200-400 miles to the southwest than compared to what the models today show for Monday. What does that mean? The reason for the drastic shift in weather potentially and the forecast.
YESTERDAY 12Z NAM MODEL RUN FOR 9AM MONDAY:
(Looked like an ice storm for us yesterday morning)
TODAY NAM 12Z MODEL RUN FOR 9AM MONDAY:
(This morning, it looks like just a cold rain)
YESTERDAY 12Z RPM MODEL RUN
(Looked like icy weather could hold on across the 278 corridor through Monday PM)
TODAY 12Z RPM MODEL RUN
(Now the model shows the potential for a line of storms)
Now that's drastic! Good thing the swing is in our favor and the threat for travel problems is significantly lower for Monday.
All and all the system looks to be faster moving, milder and wetter instead of icy across Alabama. We'll continue to monitor model trends and keep you updated just in case something changes.
There is still a slim possibility of brief freezing rain to start on Monday morning and finish on Monday evening.
