Tropical Storm Nate will bring clouds, rain and wind to the region Saturday night into Monday

 

Good Evening.  Happy Friday!

We are finally looking at a weather pattern change as we head into the weekend.  Tropical Storm Nate will impact the central Gulf coast Saturday night into Sunday.  This system will then accelerate northeastward into the Tennessee Valley Sunday into Monday.  We could see locally heavy rainfall and gusty winds across the region Sunday into Monday.

You can see Tropical Storm Nate on this satellite imagery from NOAA.

Take a look at this satellite imagery from College of DuPage.  You can see Nate as it is already bringing clouds into the southeast.  Those clouds will increase across our area tomorrow afternoon.

We had a beautiful afternoon with sunny skies and mild temperatures.  Take a look at the climate data at the Tri-Cities Airport today.

We stay dry tonight through early Saturday, but the clouds and rain chances will increase late in the day.  Here is a look at the Storm Team 11 forecast maps.

7 AM Saturday – Clouds increase through the morning.  Temperatures will be mild.

10 AM Saturday – Scattered showers will be possible to our south as tropical moisture streams north.

1 PM Saturday – Skies become clouds with breezy conditions.  Scattered showers south.

5 PM Saturday – Cloudy skies with scattered showers possible.

We are looking at the possibility for some thunderstorms Saturday night.

Look for showers and possible thunderstorms on Sunday.

Temperatures will be slightly cooler thanks in part to the clouds and rain.

Here is the 5 PM update on Tropical Storm Nate.

Take a look at the water vapor imagery – a little dry air off to the northwest of Nate.  This system has a lot of moisture with it.

The National Hurricane Center issued this map showing the potential for tropical storm force winds as Nate moves to the north-northeast.

6 AM Monday- The wind threat moves to our northeast.  We keep scattered showers in the area.

Noon Monday – Cloudy skies with scattered showers across the region.

Rainfall totals from Nate could range from one to up to four inches across our part of the country.

Winds will certainly pick up as we go into Sunday afternoon, Sunday night into the early hours of Monday morning  These maps show the sustained winds.  Winds could gust to 40 mph across the lower elevations during this time period with gusts to 60 mph possible in the highest elevations.

10:15 AM Sunday – Take a look at the forecast sustained winds.  Gusts could be higher.

We will keep the chance of scattered showers in the forecast much of next week.
