Happy Saturday! It's been a nice start to the weekend, although temperatures are a little warmer today (that means goodbye open windows, hello again A/C!). Get outside and enjoy the afternoon - and the sunshine - because rain chances will be coming back in a big way, especially as we start up the new work and school week.
Moisture and cloud cover will increase on Sunday, and that will bump up our rain chances. I'm expecting scattered rain and t-storms in both the Upstate and Mountains (although there's a little better chance of more coverage through WNC) by Sunday afternoon. The cloud cover and showers will knock temperatures back a few degrees - as highs range from the mid 70s in the Mountains to the low 80s in the Upstate.
The "main event" as far as the rain goes will come Monday and Tuesday. A low pressure system from the Gulf Coast will bring heavy rainfall to the area - as well as overwhelming cloud cover. Unfortunately, that means the dreary weather will make it a 'blah' start to the week - but after our nice, dry days I think many folks are okay with some rainy days.
You'll need the umbrella on Monday, but I think the highest chance of rain - as well as the heaviest rain - will come Monday night into Tuesday morning, during the sleeping hours. Showers continue through midday Tuesday, with shower activity beginning to taper off by Tuesday evening/night. By the time all is said and done, rainfall totals of 2-4 inches are possible. That means we'll have to watch for the potential for flooding - so keep that in mind if you live in flood-prone areas.
A cold front will meet up with the low late-day Tuesday, and behind that front we'll enjoy some nice changes. Skies will clear out Wednesday and Thursday of next week, with high temps dipping into the mid 70s for the Upstate and upper 60s/low 70s in the Mountains. The dry air means humidity will be very low, so it will again be very comfortable to be outdoors.
