Indiana Weather Outlook 1-30-17

A chilly start today as high pressure is still trying to work its way across northern Indiana to set up in central and NW Ohio by this afternoon. This will keep north winds in this morning, but we do expect a fairly quick turn in winds to the southwest behind that high. The southwest flow will begin to help temps moderate, but we don’t see our most significant warming until tomorrow. Winds become very strong for tomorrow, averaging 15-30 mph and that will take temps well above normal. We should see highs tomorrow a good 10-20 degrees above normal. The strong wind will also signal a strong front moving closer from the west.

That front impacts our weather for Thursday. Precipitation actually begins overnight tomorrow night and now looks like it could be done by mid to late morning Thursday in many parts of the state. Action may linger into Thursday afternoon down in southern and southeastern parts of the state. Moisture totals continue to get smaller and are very unimpressive at this time. We could see a few hundredths to no more than a quarter of an inch of moisture from the event, and the upper end of the range will be over the southern third of the state. This is fast becoming a non-event, with the biggest story likely being the colder push that comes behind the front. Rains can still be up to three quarters of an inch in Kentucky, but really that is the only place we see good moisture.

Those temperature levels will be most likely to be seen in east and northeast Ohio. South winds return on the backside of the high Saturday afternoon. Overnight Saturday night through Sunday a front bringing snow to a large part of the state. Temps look to fall dramatically and with the timing of precipitation starting overnight, when temps are already colder, we think we are looking at basically all snow. Temps will be below freezing over most of the state on Sunday, the freezing line Sunday afternoon all the way down to US 50 and perhaps farther south. This set up will create snow potential of 1-4” on the top end, but most of the state will be more along the lines of a coating to 2 inches. The map above shows snow potential out of the system through midnight Sunday.

Cold air remains on Monday, and we have a clipper bringing another brief spat of snow into the state on Tuesday. There we can see another coating to an inch or two over 80% of the state. Temps behind that clipper get colder and we could see some single digit to near zero readings for Wednesday morning. The rest of the week stays below normal.

For the extended period, we have another clipper bringing a chance of snow accumulation late the 8th into the 9th, another for the afternoon of the 10th, and a stronger system for the 12th. With temps staying below normal, we will be off to a cold and snowy start for the first two weeks of February.
