Changes coming in our weather - MSNewsNow.com - Jackson, MS

This week, our weather pattern will undergo some changes. Frankly, the forecast for the middle of the week and into next weekend is complicated and highly uncertain.

For tonight and Monday and Tuesday, there will be no changes. We'll have another round of low clouds and fog to deal with Monday morning. There may be some locally dense fog that significantly reduces visibility. The sun will break out mid-morning and warm us up. I expect highs in the lower to middle 80s.

High pressure will weaken over our area by Tuesday. This will come as a low pressure system, cut-off from the main upper level flow, slowly pushes through the Plains. These cut-off systems are extremely difficult to forecast and the computer models we look at don't handle them well.

After looking at all the available data, I think we will see the cut-off low stay to our west and northwest through mid week. However, moisture will slowly surge east as the high pressure over us weakens. This will aid in better rain chances by Wednesday. The slow-moving nature of the evolving weather pattern will mean once rain and storms move into our area, they may be here for a while. This could lead to some flood potential. There will also be the potential for severe weather.

Some data suggests this type of pattern may linger through next weekend. I'm not ready to bite on that just yet, so for now I will keep the forecast dry from Friday through Sunday. However, rain chances may need to be added as new data comes in and the evolving pattern becomes clearer. Make sure you check back with WLBT through the week as Barbie and Paul update the forecast. I'll also be posting updates on my Facebook page.

I do expect our temperatures to remain above normal through the next week, though they may be slightly cooler due to clouds and better rain chances.
