Weather Summary:

We are tracking another great day in the StormTrack 5 Weather Center. High pressure will slip away from the southern Appalachians, but not before leaving us with another mostly sunny and warm day. We may start the day with some fog in areas. Be on the alert for the danger of dense fog near bodies of water that could reduce visibility to less than a mile.

Tonight our clouds will be on the increase with a 20 percent chance of rain developing during the overnight.

StormTrack 5 meteorologists are tracking a strong front that will head for the Tri-Cities on Friday. The front is spawned from a storm system that is moving toward the Great Lakes. This storm system has provided quite a mix of weather events as it organized in the Rockies and northern Plains.

The front will bring a 70 percent chance of rain and possibly a thunderstorm or two. You should be on the alert for possible severe or strong storms that may carry the dangers of gusty winds and lightning strikes. The threat of severe weather is not great but possible with the strength of this system.

Rain totals will not be huge with this system, but being back over six inches below normal, any rain will be nice. Some areas could see a .25" to .75" for most of the area.

Most of the rain should move out by dark on Friday with only stray or scattered showers left for the evening.

Saturday and Sunday will be mostly sunny but certainly much cooler that before the front. We will be 18° to 23° cooler behind the front that before it passes.

Some more showers may sneak back in for Monday afternoon, although it is a 20 percent chance at best. A better chance will ride in with a front on Tuesday. We will see mostly cloudy skies and a 40 percent chance for rain.

Mid-week will return partly cloudy skies and the first half of the work week will actually be back to near normal highs for the region.

Highs will be in the mid 80s today and upper 70s Friday. The weekend has near 60 to the mid 60s Saturday and Sunday with mid 70s Monday through Wednesday. Lows will be near 50 to the mid 50s tonight and Friday night with mid to upper 30s Saturday night before climbing back to the low 40s Sunday night. Expect low 50s Monday night through Wednesday night.

Our normal high is 73°, low 48°.
