.NEAR TERM...
(Now through Monday)
Issued at 505 AM CDT Sun Jun 23 2024

The eastern periphery of the large upper ridge over the southern 
half of the U.S. will weaken through tonight as an upper shortwave 
passing over the Great Lakes region digs southward over the eastern 
states. Prior to the arrival of the upper shortwave, large scale 
subsidence and lack of moisture will result in dry and hot weather 
conditions again today.

Rain chances enter back into the forecast on Monday as a surface low 
pressure area associated with the shortwave moving eastward across 
New England on Monday sends a weak cold front southward into the 
Tennessee Valley and northern portions of Georgia and Alabama before 
becoming nearly stationary and slowly dissipates. While the front is 
not expected to enter into our area, a plume of increased moisture 
ahead of this boundary will gradually sink southward with deep layer 
moisture improving that will bring our precipitable water values as 
high 2 inches in the afternoon. This moisture combined with 
convergence along the sea-breeze and potential outflow boundaries 
will aid in the development of scattered showers and storms in the 
afternoon. A strong storm or two cannot be completely ruled out 
Monday afternoon, but we are not expecting any organized severe 
storms at this time.

High temperatures today and Monday will reach the mid to upper 90s 
(3-8 degrees above normal) inland and low 90s at the coast. Heat 
indices across much of the area today will range from 100 to 105 
degrees, and from 103 to 108 degrees on Monday. Lows will be very 
warm and humid and only lower into the mid 70s inland with upper 70s 
and low 80s along the coast, or 5-10 degrees above normal. A 
MODERATE risk of rip currents continues through the period. /22

.SHORT TERM...
(Tuesday through Tuesday night)
Issued at 505 AM CDT Sun Jun 23 2024

Upper level ridging remains centered over the Desert Southwest on
Tuesday with the local area lingering on the eastern periphery of
this feature. Meanwhile, a large upper trough to our east moves 
out over the western Atlantic. This pattern places the local area 
in a light northwesterly flow aloft on Tuesday with southwesterly
winds prevailing at the surface. Guidance continues to indicate a
plume of enhanced moisture that will be in place across most of 
the area Tuesday morning. It's possible that this moisture plume 
could get nudged further south and become confined to southern 
portions of the area during the day Tuesday as high pressure 
builds slightly over the Appalachians. While there's still some 
discrepancy with how far south this moisture gradients sags, 
guidance is suggesting that we could see some drier air move into 
northern and especially northeastern portions of the area on 
Tuesday. This drier air could help to limit rain chances in these 
areas, but for now have maintained scattered showers and storms 
across the area for Tuesday afternoon. Any showers and storms that 
develop on Tuesday are expected to follow a diurnal pattern with 
convection dissipating through the early evening hours.

The bigger concern for Tuesday will be very hot temperatures as
highs climb into the middle and upper 90s in most locations.
Tuesday is still looking like the best potential for seeing a Heat
Advisory as heat index values are currently forecast to reach to
around 105-100 degrees. However, we will continue to monitor for
this potential as drier air across portions of the area would 
have impacts on those heat index values. /14

.LONG TERM...
(Wednesday through Saturday)
Issued at 505 AM CDT Sun Jun 23 2024

Rain chances will be on the rise as we head into the middle of
this week as a weak northwesterly flow prevails. Deep layer
moisture will improve during this time as the surface ridging over
the Appalachians slides east and the upper ridging retreats
further west. A more potent shortwave trough is also expected to 
within the mean flow, with it slowly pivoting across the 
Southeastern US on Wednesday and Thursday. The lower heights and 
increasing moisture combined with another weak boundary that sags 
down into the Southeast will result in scattered to numerous 
showers and storms on Wednesday and Thursday, with isolated to 
scattered PoPs persisting into the overnight hours. By Friday, the
shortwave aloft exits to the east and very weak upper ridging 
attempts to build back into the region. This will reduce rain 
chances somewhat Friday and Saturday with much of the area seeing 
scattered showers and storms both days. It will still be rather 
warm and humid during the week with high temperature generally 
topping out in the lower and middle 90s. Heat index values will 
likely be just below Heat Advisory criteria during the middle to 
latter part of next week. /14

.MARINE...
Issued at 505 AM CDT Sun Jun 23 2024

No hazardous impacts expected as a light southwesterly to 
westerly flow will occur throughout next week. /22
