SHORT TERM
(Today through Sunday)
Issued at 401 AM CDT Sat Jul 27 2024
The strong upper level trough that has its base near the tip of the Baha will begin to cut off later today into Sunday. This will cause some changes at the local level eventually. But for now, the deep moisture will remain and the westerlies are fully in tact. Some areas will continue to get heavy rain and some areas will not. Most areas are saturated and it wouldn't take much for any one location to have flooding issues. Again, this activity should be progressive as it moves through our area, so even though there will be some heavy rainfall that could cause ponding in low lying locations and some roadways, most of this shouldn't be an issue unless there is an area that training or stalling can occur and this just isn't seen at the moment. There remains the outside chance of one of these becoming severe. The most likely probability would be the production of water/land spouts.
LONG TERM
(Sunday night through Friday)
Issued at 401 AM CDT Sat Jul 27 2024
There is some evidence of this pattern breaking down as the upper low moves NW to the Cali coast nudging the stacked SW high to the east a bit. Our area then transfers to an easterly flow regime by a as this high kicks the upper trough eastward. This will definitely cut down the precip chances, but won't zero them out. This should drop the area back to the normal hit and miss 30-40% chance of rain by the start of the new work week. This will be a transition day or two where things become stagnant as flow regime changes from westerly to easterly. During this time frame, when storms are not moving much, there would be a high chance of heavy rainfall staying over one locations for longer periods even though our rain chances are easing a bit.
AVIATION
(12Z TAFS)
Issued at 401 AM CDT Sat Jul 27 2024
Most terminals will be VFR with all having equal high chances of getting IFR in TSRA today. Coastal sites should have better chances during the morning and inland sites during the hotter portion of the day. By late evening, VFR conditons should be the rule with only one or two having vis restrictions overnight as most sh/ts activity decay.
MARINE
Issued at 401 AM CDT Sat Jul 27 2024
Outside any storms, which will be plentiful, winds and seas should be on the low side as winds should remain 10kt or less. These basic conditions should repeat through this week. Winds should become light and variable by the start of the new week with lower chances of storms around each day, but storms that do occur will still have the ability to produce strong winds.
