Warming toward the weekend. Shower chances return. Stormy next week?
Yet another mostly sunny day across the Tennessee Valley today, but it has been breezy as high pressure has shifted eastward. This has allowed winds to become more southerly, and between the high to our east and a cold front staying to our north, winds have been gusty... with gusts of 15 to as high as 30 mph at times. With the southerly winds, temperatures are beginning to moderate, and most of us have reached the mid to even upper 60s this afternoon.
The warming trend will continue for the next few days as upper winds across the area become more westerly and the southerly low-level winds continue. Many of us will be in the upper 60s, if not near 70, for Friday... and all of us look to be near or above 70 for Saturday. Overnight lows will moderate as well, coming out of the 30s and into the 40s, and maybe even into the lower 50s Saturday night ahead of the next cold front.
That next cold front approaches the area on Sunday. The timing has sped up a bit, with the chance of showers now stretching from the late morning until late evening on Sunday, with Monday looking mainly dry. Moisture looks limited, and the showers for Sunday look increasingly spotty. That front moves south on Monday, bringing a temporary shot of cooler air before the next system approaches.
The front coming through Monday stalls near the coast, never really scouring moisture out of the Gulf before that next system approaches next week. Because of that, we're starting to think that there could be a period of stormy weather with that next system Tuesday night into Wednesday. Timing is uncertain as of now, and the exact magnitude of everything is very uncertain. It is very unclear if enough moisture and instability can come northward for a severe weather threat. However, it is possible that may happen, and we will have to watch the system very carefully over the coming days.
