Fall Is Here, Sergio brings Sunday rain, then Cold Blast #2

It is no argument that Fall has finally arrived with the surge of cooler air. All of that is thanks to Wednesday's cold front that came through. We do have some changes coming in the forecast over the next seven days; however, no worries! Our cooler weather is here to remain. Instead, we do have a decent amount of rain on the way, thanks partially to Sergio.

Tonight

A weak boundary moving through this afternoon and into tonight is bringing a short lived chance at some stray rain this evening and into tonight. As mentioned, rain will be light. Likewise, the wave will be weakening as it moves through so not everyone will see rain.

Clouds that arrive with this rain will be sticking around overnight and into tomorrow. These clouds will hold in some heat tonight, preventing us from dipping into the 40s. Instead, we will see lows in the lower 50s. Rain chances drop off tonight and we remain dry until at least mid-day Saturday.

Tomorrow (Saturday)

We start the weekend dry Saturday, but Sergio, formerly a major hurricane in the eastern Pacific that made landfall in Baja California early this morning, plans to change that, along with the help of a new low pressure system. That new developing low is what picks up Sergio and brings it over to the Mid-South. The moisture from this tropical remnant will start to bring light, scattered rain as early as late Saturday afternoon. As we move into the night, rain chances quickly ramp up. Thanks to the clouds Saturday afternoon, high temps remain in the upper 60s. As it stands now, most of the University of Memphis football game vs. Central Florida should remain dry, though if rain does arrive during the contest, it will be light.

Saturday night, rain chances ramp up as steady rain moves in thanks to Sergio's remnants and a northward bound warm front from the parent frontal system that will be steering Sergio. That lifting warm front will bring in some warmer air, so Saturday night we only drop into the upper 50s to right at the 60 degree mark.

Sunday and Monday

If you thought that rain was going anywhere any time fast, you were wrong. The front takes its sweet time getting out of the Mid-South. That said, look for showers through the day Sunday, Sunday night, and into the earlier half of Monday as well. Lighter precipitation is possible during a relative lull Sunday afternoon, but look for rain rates to pick back up Sunday night.

Temps through this time will remain slightly warmer than what we've recently seen, until Monday. Sunday climbs into the lower 70s. Sunday night, as the front pushes through, temps will be dropping into the mid 50s. By Monday, the front will finally be bringing with it cooler weather, so our high around 63 will be earlier in the day.

Tuesday

Here comes some serious cooler weather, so prep for a true surge of Fall obsession! With the front moving through Monday, Tuesday looks to be the coolest part of our upcoming forecast. Lows Tuesday morning will be in the upper 40s as clouds linger. As we move through the day, there will remain the slight chance of a shower as the front finishes its exit. Meanwhile, cooler air keeps funneling in. By that afternoon, we will only top off in the mid 50s. Talk about Fall-feels!

Look for a new surge of cool air Monday afternoon into Tuesday with lows Tuesday AM in the upper 40s. (WeatherBell)

Wednesday-Friday

Wednesday starts with another chilly morning in the upper 40s for lows. In fact, Wednesday, Thursday, and Friday mornings will see lows in the upper 40s. Highs remain pleasant not only for Wednesday, but Thursday and Friday as well where we will have highs in the mid 60s. Skies conditions will vary through this period as Wednesday will see a mix of sun and clouds. Thursday will see cloud cover increasing. By Friday, skies will be mostly cloudy as rain chances start to slightly increase with the introduction of a new system.
