We've split the atom, cured polio, perfected the microchip and sent men to the moon. But I still can't tell you exactly what time it will rain today. Chalk it up to a randomly chaotic universe and variables beyond our understanding.
Ironically meteorologists do a consistently better job timing rain and snow from October thru March. Large-scale "synoptic" systems are hundreds, even thousands of miles wide with steady "stratiform" precipitation, not the hit-or-miss "convective" showers and T-storms we deal with during the summer months. These miniature thermals of rising air are 5-10 miles in diameter; they get lost in the sauce. New NOAA weather models like RAP and HRRR do a better job of predicting "windows" when storms are most likely, but timing them down to the hour or minute?
Conditions are ripe for strong to severe storms today; I expect watches & warnings close to home. The heat index will be groan-worthy, reaching upper 90s by the dinner hour. Dew points drop to more tolerable levels over the weekend with sunshine and highs in the upper 80s. Stuffy 90s return Monday-Tuesday before a cooler front of Canadian heritage has us all breathing easier late next week.

Later this water drains to the bottom of the ice sheet enabling it to move and melt faster. This makes the ice sheet more vulnerable to such rapid melt events as the climate warms, scientists say in a new study." (Photo: Sam Doyle).
