Today and Tonight:

Upper-level ridge axis centered over the High Plains and low-
amplitude shortwave trough crossing the Ohio River Valley today will 
keep our forecast area beneath northwesterly flow aloft. The 
shortwave will nudge a weak cold frontal boundary into the northern 
half of our area today. Another upper-70s to lower-80s day puts us 
right about normal for this time of year, and the slight uptick in 
moisture values will allow for isolated showers or storms to develop 
in the pooled moisture ahead of the front. With meager instability 
(500-1000 J/kg) for air mass thunderstorm potential in place along 
the moisture axis, long-lived convection is generally not expected, 
but there is a little flow aloft that should result in around 30 kts 
of deep-layer shear to help a few storms sustain during the 
afternoon hours. With expected isolated nature of convection, left 
the slight-chance to chance POPs areas generally as suggested by 
guidance (north of I-20). Continued moisture advection into tonight 
could yield some fog potential for early Thursday morning in the 
south. /NF/

Thursday-Tuesday:

A weak cold front will linger in northern portions of the CWA, 
before transitioning into a warm front and lifting northward on 
Thursday. As a result, isolated showers and thunderstorms will be 
possible for areas along and north of I-20 during the afternoon. On 
Friday, quiet and dry conditions are expected as an upper-level 
ridge begins to build over the southern CONUS. Increasing moisture 
and warm air advection is expected due to southerly flow and will 
continue into the weekend. 

A few shortwaves are expected to move along the edge of the ridge, 
bringing isolated showers and thunderstorm potential back to 
northwest MS, southeast AR, and extreme northeast LA Friday night 
into Saturday. Outside of those areas, conditions will remain quiet 
ahead of the next frontal boundary moving in from Texas. A low 
pressure center near the northern Plains and MN will push an 
associated cold front towards the area, resulting in showers and 
thunderstorms starting west of I-55 Sunday afternoon. With bulk 
shear around 20-30 kts, lapse rates near 7 C/kg, and SBCAPE 
between 600-1500 J/kg, severe weather can't be ruled out; however,
confidence is low. SPC has outlooked potential severe weather to 
the west of the CWA and we will continue to monitor for changes. 
By Monday and into Tuesday, showers and thunderstorm potential 
will cover the rest of CWA. At this time, no severe weather is 
outlooked for these days, but that could change as the timeframe 
gets closer. The aforementioned cold front is expected to push 
through our area by Tuesday evening. Weekend temperatures are 
expected to reach the middle to upper 80s and slightly decrease to
the upper 70s to lower 80s post frontal passage. /SW/

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)
