FULL-DAY TEMPERATURE DEPARTURES FROM NORMAL
Extended spell of above normal temperatures begins on Saturday
Daytime high temps are predicted to surge to/above 70-degrees each day next week, making it the warmest run of weather here to date in 2023. It’s even conceivable a temperature could approach 80 in the area Tuesday, Wednesday and Thursday next week. The expansion of warm temps over a good swath of the country is reflected in the predicted percent of the Lower 48 which is to reach or exceed 70-degrees. 17% of the country is to do that Thursday down to 11% Friday. But warming begins for the Easter weekend with 21% of the country looking for 70s Saturday and 33% Easter Sunday. By Tuesday, Wednesday and Thursday next week, those percentages will surge to 58%, 60% and 57% respectively.
Wednesday opened with the warmest temps of 2023, elevated humidities and ominous skies and active t-storms which generated wind gusts as high as 79 mph in Compton in Lee County and 66 mph at Valparaiso in northwest Indiana. Skies across the area hosted eye-catching displays of wind-tossed asperitas clouds—described as dark “doomsday” appearing clouds which look like rough ocean waters. These accompanied morning t-storms amid 70-deg temps. Chicago’s 72-degree high at O’Hare has been the year’s warmest to date. Powerful non-t-storm winds have raked the area since. O’Hare has registered a 47 mph gusts and gusts at Midway have topped out at 54 mph. Check out some of the other wind gusts observed across the Greater Chicago area:
