324 AM CDT Wed Mar 21 2018

Today and Tonight: Low cloud cover has been slow to depart northeast 
sections this morning, but temperatures there have still managed to 
fall into the upper 30s and will likely make it into the mid 30s by 
sunrise. Patchy frost may still be possible by that time there if 
the wind can calm a bit more. 

Another cool day is in store today as cold air advection continues, 
but the lack of cloud cover will allow mamximums to reach the upper 
50s and 60s. The surface high pressure ridge will settle over the 
lower MS valley this evening allowing winds to finally diminish. 
This combined with the dry air in place and clear skies should allow 
for good radiational cooling to occur. A good frost is expected over 
eastern portions as minimums fall into the low to mid 30s. Portions 
of northeast MS will fall to near 32, but this should not occur 
until right before sunrise and should last no more than an hour. 
Thus, will not issue a freeze warning for such a short duration,
but will discuss the situation in the HWO./26/

Thursday through Tuesday: The primary concerns for the period will 
be will be rain chances returning for this weekend into early next 

By Thursday morning a 1029 mb surface high will be centered over 
the ArkLaMiss area with amplified mid level ridging over the
Rockies which will provide northwest flow over the region. The 
surface high will track to the east late Thursday as we start to 
get some low level return flow Friday. A shortwave will move out 
of the southwest US which will deepen a surface low over the 
Central Plains as mid level ridging builds over the Mississippi 
Valley region on Friday. This will help to increase low level 
return flow over the region as clouds increase on Friday night. 
The return flow will increase low level moisture and bring warmer 
than normal temperatures for Friday through Tuesday. Convective 
rain chances will develop across the north on Saturday and will be
confined to mainly our northern counties through the weekend. The
cold front will stall north of the region at this time. As we get
into early next week it looks like a weak back door front will 
come into the region from the northeast. We will get some 50s 
dewpoints per GFS advancing across the region from the northeast. 
This should push off any heavy rain potential west of the forecast
area for early next week. It looks like low level return flow 
will be able to push the boundary out of the region as we move 
into Wednesday. Meanwhile, rain chances will spread across the 
region for early next week. The Euro model had a stronger back 
door front than the GFS with 40s and 50s dewpoints and it stayed 
until Wednesday. Will take a blend of both model solutions./17/

Historical Weather And Climate Facts For Today

A tornado swarm occurred in the Deep South. Between late afternoon and
early the next morning severe thunderstorms spawned 31 tornadoes in
Alabama, Mississippi, Georgia and Tennessee. The tornadoes killed 334
persons and injured 1784 others. Northern Alabama was hardest hit.
Tornadoes in Alabama killed 286 persons and caused five million dollars
damage. (David Ludlum)
Severe thunderstorms spawned thirty-one tornadoes across Arkansas,
Tennessee, Missouri, Mississippi, Alabama and Kentucky. The tornadoes
killed 343 persons and caused 15 million dollars damage. Arkansas and
Tennessee each reported thirteen tornadoes. The towns of Judsonia AR and
Henderson TN were nearly wiped off the map in what proved to be the worst
tornado outbreak of record for Arkansas. A tornado, one and a half miles
wide at times, left a church the only undamaged building at Judsonia.
