Tonight through early next week (Monday)...

Tonight-late week (Friday): A quiet night is expected across the 
region. Broad upper low centered across the Great Lakes to north 
near the Hudson Bay region is progged to sink southeast into the 
Mid Atlantic region by midweek. Some uptick in low-level moisture,
with still efficient radiational cooling overnight, will lead to
some river valley fog & psbl areas to dense fog. Added some river
valley fog potential but confidence in addition to HWO graphics is
too low to add at this time. This pattern will keep northwesterly
flow situated around the area, but as low-level/sfc high pressure
ridge build east, some uptick in moist ascent will occur. PWs 
will climb to near climatological norms, with a weak frontal zone 
diving down into Wednesday, bringing a few showers or isolated 
storm psbl. Confidence in storm coverage isn't that high. Expect
warm advection & moisture advection to pick up through the end of
the workweek, with best ascent from shortwave expected around
Thursday, where more scattered showers & some storms are psbl.
Expect moderation of temperatures, with highs near seasonable in
the upper 70s north of I-20 to low 80s to the south to seasonably
warm in the low-mid 80s by late week. Lows will be seasonably cool
tonight southeast of the Natchez Trace corridor in the low-mid 50s
while seasonable to the northwest in the upper 50s. As warm
advection picks up, highs will seasonable in the upper 50s east of
I-55 to low-mid 60s to west, especially by late week. With a
developing low pressure system in the Plains by late week,
gradient winds will be on the uptick.

This weekend-early next week (Saturday-next Monday): As H5 ridge
builds to nearly 590DM over the Gulf of Mexico, this will help
amplify the longwave pattern, with deep mean troughing for areas 
west of the MS River Valley. A strong cold core low/jet energy is
expected to eject late week into early weekend out of the High 
Plains into the Great Lakes & another strong spoke of energy/cold
core trough axis digging across the southwestern CONUS. Each are
expected to help strong lee side sfc low/deepening cyclogenesis 
to occur across the Plains, with strong tight gradient across the
Gulf Coast states. The most likely time of breakdown of the
ridging & skirting of these frontal disturbances look to be late
weekend into early next week, when the best rain & storm chances 
pick up across the area. There could be enough juxtaposition of
right entrance region/jet dynamics, mean bulk shear around
25-30kts & steep mid-level lapse rates around 7-7.5 deg C/km &
vertical totals near 27-29 deg C could support some severe 
weather potential. Can't rule out something trying to sink into 
the area late Sunday night but highest probs of some severe 
potential, per CSU machine learning probs, look to be early next
week. Right now confidence is too low to put anything in the
HWO graphics. Expect seasonably warm conditions, some +5 deg F 
above normal, in the mid 80s, while cooler by early next week, 
with lows well above climatology, some +10-15 deg F above normal, 
in the low 60s east of I-55 to mid-upper 60s along & west of the 
I-55 corridor. /DC/

Historical Weather And Climate Facts For Today

APRIL 24TH
HISTORIC WEATHER EVENTS
...1899...
Two women and one son lived to tell the story of being picked up by a
tornado and carried more than a fourth of a mile, flying far above the
church steeples, before being gently set down again. The young boy and one
of the ladies said they had the pleasure of flying alongside a horse. The
horse "kicked and struggled" as it flew high above, and was set down
unharmed about a mile away. (The Weather Channel)
...1908...
Severe thunderstorms spawned eighteen tornadoes over across the Central
Gulf Coast States claiming the lives of 310 persons. The state of
Mississippi was hardest hit. A tornado near Hattiesburg MS killed 143
persons and caused more than half a million dollars damage. Four violent
tornadoes accounted for 279 of the 310 deaths. The deadliest of the four
tornadoes swelled to a width of 2.5 miles as it passed near Amite LA. The
tornado also leveled most of Purvis MS. (David Ludlum) (The Weather
Channel)
...1925...
Louisville's and Bowling Green's warmest April temperature: 91 and 96 
degrees, respectively. Also, Lexington's earliest 90 degree temperature (90 
degrees). (NWS Louisville)
...1980...
Three of eight helicopters were damaged in a sandstorm during a 
failed-attempt to rescue 52 American hostages held in Iran. The hostages 
were later released on January 20, 1981.
...2005...
The latest measurable snowfall on record occurred across parts of Kentucky 
last year. The snow was the result of cold air and moisture wrapping around 
an area of low pressure located over the northeast United States. 
Accumulating snow was mainly confined to the ridgetops and higher 
elevations of extreme east Kentucky but at least a few flakes were reported 
just about everywhere. Some amounts reported from across eastern and 
central Kentucky  include...0.6 inches in Booneville...1.0 inch at 
Jeremiah...1.2 inches at the Jackson Weather Office...1.5 inches at 
Cumberland...4.0 inches at Lynch...and 5.0 inches at Closplint. (NWS Jackson)
