Thursday’s clear skies associated with a surface high pressure appeared again Friday. As this system moves east, increasing cloud cover in the afternoon can be expected. Breezy southwest winds at 20 mph and highs in the mid-60s are also expected.
Late Friday, a cold front will bring small showers with up to a quarter-inch possible after midnight. This cold front will knock down the highs for Saturday by nearly 10 degrees into the mid-to-upper 50s, but this incoming cooler air will help break up the cloud cover in the afternoon. Saturday evening, partly cloudy skies with lows near or below freezing could create some frost overnight.
Sunday’s weather will be mild in the day with mostly sunny skies and highs in the mid-to-low 50s. The westerly winds of the past few days will rotate easterly in the morning hours as Indiana becomes pinched between two low pressure systems to the north in the Great Lakes and south in the Gulf states. These systems will return small rain chances Sunday night into Monday morning with up to another quarter-inch possible.
Monday’s highs in the mid-50s will dip into the lower 30s in the late evening, as both a surface low pressure system near the Great Lakes and a surface high pressure system to the west in Minnesota will funnel some of the cooler northern air downward into south-central Indiana. The low will migrate eastward out of the region after dawn on Tuesday, and the high will steer its way directly overhead Indiana by the afternoon, allowing for sunny skies and gradual warming throughout the day back into the mid-50s on Tuesday, and into the mid-to-upper 60s on Wednesday and Thursday.
Continued rain showers and threats are possible on Wednesday night into Thursday morning as a cold front sweeps across the state. Then another area of high pressure moves in Friday, clearing skies and potentially warming the air mass.
