FINALLY, A SUMMERY DAY SPRINKLED WITH STORMS...
The dog days of August never showed up this year. Those hazy hot humid days the month is known for have been few and far between. The hottest day so far this August in Cedar Rapids has been 87 and that was way back on the 4th. We've now gone 8 consecutive days without an 80 degree high. You can see the August 2019 temperature departures and the dominance of cool air in the central U.S.
The streak of 8 days without an 80 should come to an end Thursday as a quick surge of warm air surges northward ahead of a cold front. Most of my area should end up with highs in the low to mid 80s. The EURO shows this.
The southerly winds that bring the warmth will also draw in some moisture. Dew points should get into the upper 60s before the front arrives.
