336 pm cdt Tue mar 19 2019

Discussion Overall it was fairly quiet here. There are a few
interesting things to look at on satellite across the region but the
weather is the quietest it has been in a while and we look to remain
rain free through much of the forecast.

So we had a weak front move through last night with the main impact
being drier air. This led to rather dry conditions across the region
today with a few locations seeing the rh drop below 20% but will
also allow for the area to see lows tonight around 5-10 degrees
below normal. Temps at h925 will remain around 8-10c with highs
tomorrow ranging in the mid 60s to near 70.

Strong S W over the NE panhandle will work sse through the plains
and across the lower ms valley Wednesday night. This will bring a
wind shift through the area but this will be dry system for our
area. In fact the only real impact will be winds shifting out of
the northwest for a short time frame but the wind field completely
breaks down as high pressure at the sfc works over the area
Friday. This should continue to allow for cool morning lows
heading into the weekend but by late Saturday we will finally see
return flow and dewpoints will slowly start to rise. Ll temps will
also begin to inch up and highs will be back in the 70s this
weekend.

As for rain it looks like the next best chance will be early next
week, possibly as early as Monday night but maybe more so Tuesday.

Models are advertising the next disturbance moving across the lower
ms valley Tuesday. There may be some timing issues but this may
bring a shot of strong storms and a few could be severe. It is late
march so can not rule out the possibility of severe weather with
these systems. Cab

Aviation VFR conditions prevail at all area airports. There is
not expected to be any reduced visibility or changing conditions
through tonight into Wednesday. Msw

Marine
There is a high pressure system in place over our area. Currently
the winds have a northerly component. As the high pressure moves
eastward through the week, the winds will shift to have a southerly
component with more onshore flow. There are not expected to be any
headliners today into tomorrow. Msw
