3/24 – Rob Knight’s “Heavy Rain Continues” Afternoon Forecast
A boundary south will lift northward as the Arizona impulse begins lifting to the northeast. This will produce another round of showers and thunderstorms late this afternoon or evening. Pretty much the entire area has seen at least 2 inches of rain in the last 24 hours, with the southeast half of the area in excess of 4 inches. Any prolonged heavy rain in the area will most likely be almost entirely runoff and likely to cause issues.
The Arizona disturbance will lift into the southern Great Lakes by Thursday evening with one final round of convection during the afternoon into the early evening hours. Certainly sufficient instability and shear for a few strong to severe storms, and another brief round of heavy rainfall.
Friday will be a day in between systems as boundary shifts east and south of the area with little or no precipitation expected.
