Discussion
A relatively calm and quiet forecast lies ahead for atleast the
next 5 to 7 days, with the main focus switching to the upcoming
memorial day weekend with building heat. Taking a quick look at
the upper-air pattern reveals a persistent ridge axis anchored
from the southeast, extending north across the great lakes which
has kept a nearly stationary surface high right along the atlantic
coastline. Each day will be relatively redundant, beginning with
developing patchy cumulus in the mid-morning hours with a
northward drifting seabreeze across the northshore and ms gulf
coast. Short-range cam guidance is not really suggesting much in
the way of pop's for the next few days, as model soundings
illustrate a persistent low mid-level subsidence inversion aloft
keeping most convection from developing. However, any localized
convergent boundaries may supply enough lift to help pop up an
isolated shower, but widespread heavy rain precipitation is not
expected through early next week. Additionally, some areas of fog
may develop north of the ms coastline and across southern ms
early tomorrow morning, but should not be overly widespread or
dense enough to cause significant impacts at this time.

By this upcoming weekend, mid-level height anomalies will
continue to increase per latest gfs ECMWF trends, with a generally
stationary h5 ridge center of 591 594dm situated right along the
northern gulf coast. This will help press afternoon highs into the
lower to mid 90's and soar heat indicies to the upper 90's to
possibly 100's. Main takeaways for this memorial day weekend will
be taking necessary heat precautions, especially for those with
outdoor activities. Beyond early next week, long-range guidance
and run-to-run consistency is beginning to hint at a possibility
of this ridge breaking down, which might drag the heat back down
to near climatological normal late next week. Klg

Marine
Onshore flow remains in place through the rest of the week and
weekend, thanks to a nearby surface high pressure area. Not
expecting any significant marine hazards for the next 5 to 7
days, as winds will likely remain below small craft exercise
caution criteria and waves ranging 1-2 feet near coastal 3-5 feet
for outer marine zones. Klg

Aviation
Latest visible satellite imagery and surface observations across
the region continues to illustrate a persistent CU field across a
large majority of the area, with few sct cig's ranging between 020
and 035. These clouds will diminish later this evening withVFR
conditions for all terminals through just after midnight. Only
potential hazard to speak of will be patchy fog early tomorrow
morning, as latest guidance suggests light fog temporarily
reducing flight categories. Good news is this fog should not be
very dense, or dense enough to cause long- term impacts with
improving conditions shortly after sunrise. Klg
