Short term /today through Tuesday/...

Other than high clouds and well above normal temps, no weather
impacts expected during the short term period. Recent model guidance
still indicating weak upper low remaining over the northern Gulf
Coast area next 48 hours while Maria churns slowly north toward the
NC Outer Banks. In between, fairly dry air mass and subsidence. Max
temps on Tuesday could be above 90 in many areas, though the
guidance blend keeps upper 80s. Have tweaked the blend up a degree
but wouldn't be surprised if we end up higher. Even if that
occurs, record temps (shown below) are not likely

Long term /Tuesday night through Sunday/...

Medium-range models remain fairly consistent with recent previous
runs through the extended forecast period. Still looking at a warm
and dry start to the forecast as the region remains under the
influence of a large upper-level ridge. Ridge breaks down as we head
into the weekend as an upper-level trough moves into the Great Lakes,
Ohio Valley and northeastern U.S. Models have backed off somewhat on
the amount of lowering we should see in thickness values and on how
dry the airmass will become over the region, but we are still looking
at a return to more seasonal temperatures by the end of the period.
Weak, "orphaned", upper low over the northern Gulf of Mexico may
bring some precipitation chances back into the region as well over
the weekend and into the beginning of next week.
