National Weather Service Shreveport LA 120 AM CDT Sat Apr 20 2024 ...New AVIATION... .UPDATE... Issued at 1013 PM CDT Fri Apr 19 2024 The evening sfc analysis indicates that our cold front has drifted S into upper SE TX and Cntrl LA, after having been stationary for much of the day along the I-20 corridor of N LA into Lower E TX. While this front may drift a tad farther S overnight, cool advection will remain minimal, with temps not expected to fall off as much as was previously advertised. Meanwhile, weak overrunning has commenced this evening atop the very shallow air mass in place (near or less than 1kft deep per the 00Z KSHV raob), with areas of -RA having developed over the last couple of hours over portions of NE TX into SW AR. Also beginning to see areas of -RA developing over NW TX/SW OK, near an area of PVA traversing atop weak convergence along an inverted H850 trough that extends NE into Srn and SE OK. As the PVA increases from the W overnight, should see an increase in convection late, especially over the Nrn third of the area as the H850 trough bridges E into Srn AR, with additional development occurring along an inverted H925 trough extending farther S into Lower E TX into N LA. Thus, the current pop forecast of high chance/likely still looks good late over these areas, becoming more widespread after daybreak Saturday once convergence in maximized between the H925-850 troughs. As was the case last night/this morning, the NBM was much too cool with overnight temps within this very shallow air mass, with the warmer HRRR/NAM 2M temps doing a seemingly better job with temps. Thus, have trended the forecast more in line with these higher resolution progs, having raised min temps several degrees as a slightly tighter pressure gradient overnight will keep the winds up and the air more mixed, not allowing the air mass to completely saturate. Did not make any changes beyond tonight, as minimal warming is expected generally along/N of I-20 Saturday as periods of convection continue. Zone update already out...grids will be available shortly. 15

A spring storm produced unusally heavy snow in northeast Ohio. Warren received 35.5 inches in thirty-six hours, and 28 inches fell at Green Hill. Akron OH established April records of 15.6 inches in 24 hours, and 26.6 inches for the month. Pittsburgh PA established April records of 12.7 inches in 24 hours, and 13.5 inches for the month. (David Ludlum) (The Weather Channel) ...1920... Tornadoes in Mississippi and Alabama killed 219 persons. (David Ludlum) ...2002... An unseasonably warm and moist air mass had settled across eastern Kentucky leading to record breaking temperatures at the Jackson Weather Office and the London Corbin Airport between the 16th and 21st of April. Jackson saw several days in a row with record high temperatures as well as maximum low records. On the 19th the mercury soared to a record high of 89 degrees at Jackson and a record tying 87 degrees at London. The low temperature at Jackson was a balmy 69 degrees good enough for a daily as well as a monthly maximum low temperature record. (NWS Jackson)
