(This evening through Wednesday night) Issued at 347 PM EDT TUE MAY 22 2018 Available shortly... .LONG TERM...(Thursday through Tuesday) Issued at 347 PM EDT TUE MAY 22 2018 The period will begin with upper level ridge stretching from the Southeast US into Canada. This combined with surface high pressure will keep the area mostly rain free through Thursday. This high amplitude ridge will suppress through the period, as a short wave trough develops across the Upper Midwest. Then by the end of the period we could see some interaction from a tropical system developing in the Gulf of Mexico. The weakening upper level ridge and interaction with Gulf Moisture will allow for at least isolated to even some periods of scattered thunderstorms for much of the end of the period. Given the more summer like pattern the peak chances would be in the afternoon and early evening with the day time heating. The lack of shear will keep much of this activity unorganized, and by the weekend into early next week the PWATs increase such that more heavy rainfall could come from any thunderstorms that develop.
