Tonight and Thursday: Afternoon satellite imagery showed a well
defined cu field nearly along the Mississippi river where an axis of
moisture resides. Daytime heating of this moisture axis has led to a
few light showers showing up on local radars mainly over the delta
region. This convective activity is expected to remain over our
delta region and as far south as Vicksburg. This activity will
also dissipate by early evening. Also noted on satellite imagery
was the circulation around a shortwave trough to our east and a
large upper level ridge to our west. This will maintain northwest
flow aloft across our CWA through Thursday. There was a
disturbance within the northwest flow aloft over the central
Plains that will bring some mid and high level clouds across our
CWA tonight into Thursday but no rain is expected. As the upper
level troughing to our east continues shifting east, the large
upper level ridging over the central CONUS will shift east as well
and become dominant over our CWA. This will help continue our
warming trend and allow temperatures to top out warmer than
normal; in the low to mid 90s. Our normal highs run in the upper
80s. In addition to the ridging aloft, surface ridging from the
northeast will continue across our CWA. This will continue to
limit the return of deep moisture over our CWA and help keep
morning lows slightly warmer than normal as well. Our normal lows
run in the mid 60s.
Thursday night through Tuesday night: Come Thursday evening the
omega block with ridging over the central CONUS and troughing over
east and west will still be in place. This pattern looks to last
through Monday even as the ridge axis shifts to become centered
nearly over the Mississippi river. The surface ridging from the
northeast will continue over our region as well. This will
contribute to a warming trend through the period with highs topping
out in the mid to upper 90s by Monday. The surface ridge will
continue to help limit moisture return and although it will be hot,
the lower relative humidity will mitigate and heat stress concerns
as peak heat index values look to remain below 105F. The latest
Drought Monitor showed abnormally dry to moderate drought conditions
across our northern zones. Without any rainfall in the forecast
along with the hot temperatures, conditions are expected to worsen.
