Severe Storms on March 27-28, 2014 (Pg1)
 
Southwest winds at 500 mb (18,000 feet) drove a storm system ("x") and associated trough (dashed black line) into the middle of the country at 700 pm CDT on 03/27/2014.

Heading into late March, the pattern changed from a flow out of Canada (cold) to a southwest (mild) flow aloft (subtropical jet). A storm system rode the flow from the southwest United States through the central Plains and the upper Midwest on the 27th.

In the picture: Southwest winds at 500 mb (18,000 feet) drove a storm system ("x") and associated trough (dashed black line) into the middle of the country at 700 pm CDT on 03/27/2014. Ahead of the system/trough, low level south winds brought moisture northward from the Gulf of Mexico. Dewpoints reached at least 60 degrees F (green shading) in southern sections of Arkansas.

 

As the system went by to the north/west of Arkansas, moisture was drawn into the region by strong southerly winds in the low levels of the atmosphere. Temperatures warmed into the 60s/lower 70s. Warmth and moisture helped fuel developing thunderstorms.

 

During the afternoon, a large area of showers and thunderstorms materialized, and produced heavy rain from central into northeast sections of the state.

The satellite showed widespread showers and thunderstorms (Round #1 T-Storms) crossing the Mississippi River, with new storms (Round #2 T-Storms) popping up in southwest Missouri at 645 pm CDT on 03/27/2014.

Precipitation amounts topped an inch at a few spots. This included Des Arc (Prairie County), Little Rock (Pulaski County), Sheridan (Grant County) and West Memphis (Crittenden County).

 

A storm system ("L") in northern Illinois will drag a cold front toward Arkansas at 700 pm CDT on 03/27/2014.

Toward evening, the first round of showers and storms ended, but a cold front loomed to the northwest. The front triggered a narrow band of storms in northern and western Arkansas.

 

Chances for severe weather on March 27-28, 2014.

This latest round of storms did not provide much rain, and tended to weaken as the night progressed (as daytime heating was lost).

As the 27th ended, there was no severe weather reported locally. Severe storms did fire up in western Missouri. There were numerous instances of hail (to the size of hen eggs), and a few tornadoes were likely spawned. This is where the aforementioned storm system interacted with the front, and enhanced lift (upward motion) to promote storm growth. Such an interaction was expected around here the next day.

 

Severe probabilities in late March are usually highest from the southern Plains into the southeast United States.

The front stalled across the area early on the 28th. As the front parked, fuel (warmth/moisture) levels grew across the southern half of the state.

 

Temperatures in the south climbed into the 70s to lower 80s.
