Don't let Spring's greenery and budding flowers catch you off guard.
A cold front is pushing through South Mississippi over the weekend, though it won't be the "snowpacolypse" forecast to envelope much of the nation. Three separate storms will cause bitter cold and snow around two-thirds of the nation as a polar vortex blasts its way toward the Atlantic seaboard, mashable.com says.
For the Mississippi Coast, that means rain showers, a slight chance of severe thunderstorms and cooler temperatures at night, the National Weather Service says. There's also a possibility of hail, damaging straight-line winds and a tornado.
There's an 80-percent chance of precipitation Saturday, with as much as a quarter to a half an inch of rain possible.
The regions most likely to have severe thunderstorms are along and north of the Interstate 10 corridor, including the coastal counties.
The chance of rain decreases to 20 percent overnight and into Sunday, with a 40-percent chance of rain on Monday.
Weekend temperatures will be cooler than they normally are this time of year. The average temperature in Biloxi, for instance, is 77 by day and 61 by night, according to accuweather.com.
Forecasters expect high temperatures of 70 on Saturday and 67 on Sunday.
Overnight temperatures will drop to 45 on Saturday night and to 57 on Sunday night.
On Monday, there's a 40-percent chance of rain. The high is expected to reach 75, with a low of 59 overnight.
If you've packed up your light jackets, you may want to pull them back out — and put them near your umbrella or rain coat.
