Scattered light precipitation lingers over the state today. If we compare today’s expected action with yesterday, there really is no comparison. Today’s action will be very light – we expect nothing more than a few hit and miss showers and sprinkles giving a few hundredths to at most a tenth over 60% of the state. Most of that will be done by mid afternoon at the latest. But, it is enough for a damp feel, and we can’t call it a dry day by any stretch of the imagination. Temps today should move upwards, and be above normal, but strong wind will keep if from feeling that mild.
Cold air arrives tomorrow morning, blasting in from the NW. We expect normal to below normal temps for the weekend, both Saturday and Sunday. However, we are taking the chance of flurries in northern Indiana out of the forecast for overnight tomorrow night into early Sunday and instead will be completely dry. High pressure centers over SW Indiana around sunrise Sunday morning.
Rain starts to surge north Monday morning as we start the week. Rain starts in southern Indiana, but by midday will cover most of the state, and by mid-afternoon we see 100% coverage. The rains are impressive too. We are raising rain totals to .25”-1.5” for the entire state, even northern areas that will see the smallest totals now easily get above a quarter of an inch. The map at right is a snapshot of the set up the afternoon of New Year’s Eve. The rain will be most intense in southern Indiana. Action is done by shortly after midnight across the state, but still, if you have plans for the evening…prepare to be wet. Temps will be mild again, and we are looking at the entire precipitation event to come in the form of rain. Significantly colder air returns for New Year’s Day on Tuesday.
Dry weather remains in control for the rest of the week. We can’t rule out a few flurries Wednesday over the northern third of the state, but this will be very hit and miss and not a big deal. Dry weather stretches through Saturday and into early Sunday. Our frontal complex for Sunday the 6th may end up being delayed about 12-18 hours or so, arriving late in the day or even for Monday the 7th. Moisture potential remains limited, at .1”-.4” and coverage of 60%.
Colder air returns behind that system, with potential for temps to go 10-20 degrees below normal from the 7th through the 9th. Temps begin to moderate closer to the 10th, and another front brings chance of scattered snow showers around the 11th.
