Hot, humid and dry weather will persist through Monday as an
upper level ridge remains over the region. Lows the next few
nights will be in the 70s with highs in the low to mid 90s.

.SHORT TERM...(Today through Monday)
Issued at 109 AM EDT Sun Jun 17 2018

The upper level ridge was really holding convection in check with
large scale subsidence over the area. Will continue the heat
advisory issued earlier with temps rising close to 95 this
afternoon with corresponding heat indices close to 100. The heat
advisory may need to be extended MOnday, but for now have deferred
this decision to subsequent shift/s as temperatures may be a few
degrees cooler.

.LONG TERM...(Monday night through Saturday)
Issued at 109 AM EDT Sun Jun 17 2018

A more unsettled pattern is just ahead as the upper level ridge
breaks down. Precipitable water values will become substantial,
with the GFS pushing 2.3 inches Monday evening as moisture pools
south and in the vicinity of the front. Climate maxes per SPC
climatology page interpolates to around 1.85 inches for Jun 15-20.
The front will move south and become stationary over or near the
forecast area, and also become the focus for storms. Heavy
rainfall is possible, especially if there is any training of
storms. Temperatures will be closer to normal by the middle of the
week, especially north of the front.

.AVIATION...(For the 12Z TAFS through 12Z Sunday Night)
Issued at 654 AM EDT Sun Jun 17 2018
