Our weather pattern looks fairly “unsettled” for the next week, more so in the north than the south at the outset, but in general, we all see some pretty decent rain between now and the end of next week. We offer no changes to the general forecast this morning. Moisture is spreading into northern Indiana today as an upper level disturbance moves out of the Upper Midwest and into the Great Lakes. This will bring rain in to the state from I-70 northward. WE look for a few hundredths to at most .3” with coverage at 70%. The best coverage will fall the farther north you go, particularly near the Michigan line. South of I-70 we see nothing. Scattered showers linger for Saturday from US 30 northward. That round of moisture amounts to only a few hundredths to a tenth or two. We still think clouds mix with sun down to SR 26, and then south of there we see mostly sunny skies for Saturday.
A frontal complex sags through the state on Sunday. The northern part of the state actually sees some thunderstorm chances for this still Saturday night around midnight, but then it slowly works south. The front may try and fall apart a bit over southern Indiana, but we don’t want to take rain chances out anywhere at this time. Most of the rains for Sunday on into the overnight will produce a few hundredths to .4” with 40-50% coverage. Stronger thunderstorms may try and fire off early Sunday morning and in the northern part of the state, boosting rain totals there, and then again Monday morning in west central and southwest Indiana.
We can’t rule out scattered showers for Monday and Tuesday, but coverage will be at 30% of the state or less. Then action ramps up later Tuesday afternoon and overnight. That round of moisture can bring .05”-.5” with 40% statewide coverage.
We should be dry for next weekend, but then in the extended period, we are watching a front sliding in from the NW around the 21st. We are leaving rain totals alone with this front, looking for .25”-1” and 80% coverage.
