Increasing Moisture May Produce a Better Shot of Rain

A frontal system will bring us an increase chance for rain this week. Hello, I'm Chief Meteorologist, David Sawyer.

The high pressure system that has kept us dry the past week will move eastward, allowing moisture to gradually return to Alabama with warm, southeasterly winds.

Tuesday and Wednesday, a frontal system will slowly approach central Alabama. This will increase our chance of rain slightly on Tuesday with highs near 80.

Then, on Wednesday, the chance of rain will increase further as this frontal system gets even closer to us. At this time, it does look as though the system will begin to weaken somewhat as it approaches Alabama. Consequently, although our rain chances will increase, expect only scattered showers and thunderstorms for the middle part of the work week.

Another storm system gets cranked up in the pacific northwest which will drop another cold front into central Alabama by the end of the week. This system will bring us a little better rain chances with it on Thursday and Friday. However, the forecast remains very tricky. Both the GFS and NAM forecast models are turning up with very different solutions as far as our rain chances this week. The GFS is significantly wetter than the NAM so there is some major disagreement. The models have been flip flopping the past few model runs, but I'm hopeful that we will see some beneficial rain towards the end of our work week.
