MERIDIAN, Miss. (WTOK) - After a few morning showers, we have stayed mostly dry on our Tuesday. As we close out the remainder of our daylight hours, a few showers and storms may still fire up across our area. Most of us will remain dry, but be sure to still keep an eye to the sky if you plan to be outdoors while the sun is still out. We’ll see partly cloudy skies tonight with Wednesday morning lows in the mid-70s. Wednesday will be the warmest day of the week with highs in the low-to-mid-90s and heat index values topping out around 102. Scattered showers and storms will develop Wednesday afternoon, but many of us will still remain dry under partly cloudy skies.

A disturbance called a “mesoscale convective system,” or MCS for short, will drop into our region Wednesday night. This system will be weakening as it approaches our area, but an isolated 60 mph wind gust will be possible late Wednesday night and into our day on Thursday. Thursday will feature our best chance of rain and storms this week as highs stay in the low-90s. A weak area of low pressure will keep rain chances in the forecast for Friday as scattered showers and storms will remain possible in the afternoon.

For Independence Day, the aforementioned area of low pressure will keep scattered showers and storms in the forecast. These storms will be driven by daytime heating and thus will begin to weaken and fizzle out once the sun sets. Highs on Saturday will be in the low-90s with heat index values generally staying below 100. If you have any morning plans on the Fourth of July, you are looking a-okay. Heading into Saturday afternoon, showers and storms will develop so be sure to keep an eye to the sky. It will not be raining all afternoon long. Some of us may not even end up seeing any rain at all. In sum, you won’t need to cancel any outdoor activities for Independence Day. Just be sure to follow the usual summertime thunderstorm precautions (when the thunder roars, go indoors). Once the sun sets and storms dissipate, you should be good to light some fireworks to celebrate the signing of the Declaration of Independence.

Storm chances will increase heading into Sunday, Monday, and Tuesday as an area of low pressure continues to keep plenty of moisture in place over our area. Morning lows during this time frame will remain in the low-70s, with afternoon highs in the low-90s. Heat index values will generally stay below 100 degrees each afternoon.
