Once again, not a lot to talk about today, but things are going to change soon. Precipitable Water Values will remain 90-100% of the average for this time of year.
Later tonight, those values will tick up slightly to around 110%. They will continue to increase on Wednesday into the 120-130%+. By Friday, those values will climb to 150% of average.
What this means is tomorrow’s precipitation chances (POP’s) will increase for afternoon thunderstorms. You know the drill: Thursday’s chances will be higher than Wednesday’s. Friday’s chance will be higher than Thursday’s, and so on. Dewpoints finally climb into “the zone” by Thursday or early Friday.
That pattern will remain in place for about 5 days as models show another short-term dry period beginning Tuesday or Wednesday (8/25- 8/26).
