A look at Saturday morning weather features show a cutoff upper low spinning over the north central Gulf. A disturbance over Missouri is diving southward.
Easterly flow and moisture values will continue to rise today with rain chances increasing form east to west. The highest rain chances will occur during the heat of day this afternoon and evening.
Partly to mostly cloudy conditions will prevail with scattered showers and thunderstorms possible state wide.
Daytime high temperatures will be several degrees below normal due to the cloud cover and rain.
Rain chances will slowly decrease on Sunday…generally from southwest to northeast…as the upper low lifts northeast over the Appalachians.
By Monday…with no real lifting mechanisms present, conditions should be dry across much of the area with a slight chance of scattered storms.
We will be watch what happens to Tropical Storm Erika. The latest forecast from NHC has Erika weakening as it moves over Cuba with a small chance of it restrengthening over the Eastern Gulf of Mexico.
At this time, no major impacts are expected here in Alabama. Adjustments to rain chances may be needed based on future changes to the track and intensity forecast by mid to late week.
An easterly flow has pushed clouds into eastern sections of Alabama.
The flow will continue to set up across the area. This will allow us to gradually moisten up the next couple of days.
An isolated shower or thunderstorm is possible Friday afternoon over eastern sections of the state.
By Saturday, a weak upper low sets up over the deep south as a shortwave passes through the Midwest. The setup will allow for better coverage of showers and storms during the day Saturday.
Eastern sections of the state look to be more favorable for scattered storms as a ‘wedge front’ moves west to east from Georgia.
By Sunday…the shortwave will move northeast out of the area. The coverage of scattered showers and storms should be a little less and temperatures a little warmer.
We are watching future developments in regards to Tropical Storm Erika. At this point, we don’t expect to see any rain from the storm. However if the storm were to track further west than projected, the forecast will need an update.
High pressure over the northern Plains is allowing a northerly flow to advance cooler and drier air into the southeast U.S.
A huge difference in the temperatures and dewpoints are forecast for the state as the summer heat and humidity takes a break.
A nice string of dry days with cool mornings and seasonably warm days is ahead. Afternoon high temps should still climbs into the 80’s…with below normal early morning lows.
Overall, the weather will be beautiful for late summer through the rest of the work week.
As we look ahead, southerly flow will return around Sunday and we could see some scattered showers back into the forecast.
The humidity and scattered thunderstorms over the weekend will be replaced by dry air from a cold front moving into the region.
The front will move into Alabama today with a slight chance of scattered storms along or ahead of the front.
Behind this front, dry air will filter into the state and end the thunderstorm chances.
Sunny skies and dry conditions will prevail through the work week…as the cooler airmass settles into the area.
North and central sections will experience the most of the cooler weather, however the entire state will see drier and more comfortable weather.
The cooler temperatures will be most noticeable during the overnight and early morning periods.
