Weather Pattern Summary:
High pressure ridging over the Northeast US this week will continue to increase our temperatures to milder and slightly above average levels for afternoon highs and overnight lows for the majority of this week. There will be a couple of opportunities for precipitation this week, as we approach the holiday timeframe.
The Next Storm System:
A tendency for more of a dip southward in the jet stream over the Western US will begin to focus colder and stormier conditions there, and bring rainfall and snowfall to portions of the Cascades and Rockies. A couple pieces of energy will break off that main trough and march across the Southern US during this upcoming week. A storm system may bring about severe weather in parts of the Plains and Deep South. Concerning later Tuesday, the risk area makes it into much of the Tennessee Valley. Here’s the latest outlook from the Storm Prediction Center for Tuesday:
At this time, we are expecting a broken line of showers and/or thunderstorms to make it into the Tri-Cities sometime Tuesday night or Wednesday. At this time, the risk of any impactful storms seems to be focused from Memphis to Nashville. Cities as far east as Knoxville have a low chance of isolated severe storms, with little to no risk in the Tri-Cities and the general vicinity nearby. Stay tuned for any possible adjustments to the forecast. Temperatures remain fairly mild much of the week with highs in the upper 60s to mid 70s, and lows in the mid 40s to lower 50s.
Halloween Sneak Peak:
Another round of possible showers and storms will arrive by later this weekend and rain chances may carry into Halloween with highs in the 60s, but stay tuned as there will likely be multiple adjustments to the forecast between now and then.
