An active weather pattern is setting up for overnight Sunday and the first half of Monday. This stormy period will be followed by a significant drop in temperatures that will stick around for at least the next week.

Starting with tonight, a cold front moving through Arkansas and northeastern Texas will continue eastward through Louisiana, Mississippi, and Alabama overnight. A surge of moisture generated some spotty showers over our area this afternoon, but the showers diminished after sunset. Some of the more robust showers down I-59 from Laurel to Poplarville had some bulky scud clouds with them. Scud clouds are often mistaken for tornadoes, and several reports of tornadoes (probably false reports) have been coming in from areas in southern Mississippi. We do NOT expect tornadoes or any other form of severe weather in our East Mississippi and West Alabama viewing area. Instability is elevated, which suggests there may be some lightning and thunder, but the instability will be decreasing as temperatures cool after sunset and the line of storms actually approaches. Most of the overnight activity will likely be spotty as opposed to widespread. Most models suggest the more widespread rain will begin around 3-4 AM Monday for our western areas (Louisville to Philadelphia to Newton to Bay Springs) and straddle the state line (near Meridian, Quitman, DeKalb, York, and Lisman) around 6-8 AM and then exit our eastern areas in West Alabama around 1-2 PM.

With the rain's end, a cold front will sweep from west to east across our area and open the door for much colder air to flow into our area. Monday night's temperatures will be considerably colder, but a little wind just above the ground should help to mix the lower atmosphere and prevent a bitterly cold night. High pressure slides in from the west on Tuesday, and will mean 20's and 30's for Tuesday and Wednesday nights. That high pressure will head east, and temperatures will begin warming slightly once the high's center is east of us on Friday and Saturday, but another cold front could mean some more rain for us on Saturday.

TONIGHT: Cloudy with spotty showers, then rain and thunderstorms likely after 2 AM. The low will be near 62. The wind will be from the south at 6-12 mph. Sunset is at 4:50 PM.

TOMORROW: Rain and thunderstorms in the morning, cloudy in the afternoon. The high of 66 will occur around sunrise, and temperatures will steadily cool throughout the day. The wind will be from the northwest at 7-14 mph. Sunrise is at 6:46 AM.

TUESDAY: Partly sunny with a slight chance for rain in our extreme southern areas. The morning low will be near 31. The afternoon high will be near 52. The rain chance is 20%.

WEDNESDAY: Partly sunny with a chance for rain in our extreme southern areas. The morning low will be near 32. The afternoon high will be near 55. The rain chance is 20%.

THURSDAY: Sunny. The morning low will be near 25. The afternoon high will be near 59.

FRIDAY: Mostly sunny. The morning low will be near 30. The afternoon high will be near 62.

SATURDAY: Mainly cloudy with periods of rain. The morning low will be near 45. The afternoon high will be near 65. The rain chance is 50%.

SUNDAY: Mostly sunny. The morning low will be near 39. The afternoon high will be near 61.
