Watches, Warnings & Advisories for Sunflower Co.

Saturday, January 12, 2013

Storms & heavy rain tonight

There's a lot going on weather-wise this weekend!  Flooding, possible severe weather, and a chance of wintry precipitation early next week make for a lot of information to process.  First, let's look at what watches and/or warnings are currently in effect:

A FLASH FLOOD WATCH is in effect for much of the area from 6:00pm tonight through 6:00pm Sunday, January 13, 2013.
A FLOOD WARNING is in effect for the following:  The Sunflower River at Sunflower, MS; the Big Black River in Attala & Holmes counties; the Yalobusha River at Whaley for Carroll & Leflore counties
An AREAL FLOOD WARNING in in effect for Leflore and portions of Northwest Carroll counties until 2:45pm today, January 12, 2012. 

As for the weather this weekend and early next week, severe weather and flooding are the primary hazards we'll face Saturday night into Sunday morning.  That will be followed on Monday & Tuesday by a potential for sleet and freezing rain.

Late this evening and into Sunday morning, storms capable of producing damaging 60mph winds and tornadoes will be possible across Northwest Louisiana, Southeast Arkansas and the Northwest Delta area of Mississippi.  Heavy rains of 2 to 3 inches are possible along and northwest of an axis from Winnsboro, LA to Grenada, MS, with locally heavier amounts possible.  With saturated grounds from this week's 5-7 inch rain totals, the additional forecast rainfall will exacerbate existing flooding in many areas.  Rainfall rates will taper off as the cold front pushes south of the area, but this cold air raises the possibility of wintry precipitation early next week.

This cold airmass will be over the area by late Sunday and remain for the first portion of the week as the front stalls over the region.  While some uncertainty exists as far as timing and intensity, forecasters are monitoring closely the potential for freezing rain and/or sleet from Monday into Tuesday.
