Indiana Weather Outlook 4-18-18

Increasing clouds today as low pressure moves into east central IL this morning. This low will bring moisture back into the state shortly after midday, and we will see on and off showers tracking mostly across the northern part of the state through the late afternoon, evening, and overnight and into tomorrow morning. Moisture does not look that impressive, still under a quarter of an inch for the most part, although a few locations may push closer to a third. Liquid precipitation it expected through the daylight hours, but temps fall tonight, meaning after midnight we may be able to see some mixing or change over to light wet snow. We do not expect any problems, and the wet snow will be limited in coverage. Precipitation in generally will mostly be over the northern third of the state, although we will allow for some afternoon scattered showers down to I-70. South of 70 we see nothing.


We dry down and see clouds break up tomorrow afternoon and se should see sunshine in full force ahead of sunset. We then keep a dry pattern in our forecast dry for Friday through the weekend and for most of next week. The chances of precipitation for Tuesday continue to fall off, and at this point, we think that we end up with nothing but clouds and a few spits or sprinkles over southern Indiana Tuesday afternoon, and nothing anywhere else. The dry weather then continues for Wednesday, Thursday and Friday.


There is still a good chance of moisture with a strong system around the 28th into the 29th. Moisture totals are not as impressive this morning, but we still are leaving the door open to some rains from .25”-1” over 70% of the state. Then we have an unsettled finish to the 11-16 day forecast window. Models are unsure how to handle moisture, but we do expected at least one more strong front between the 2nd and the 4th. The front likely has some strong to severe weather potential and can bring rains up to 1”. Timing is the main uncertain part to precipitation in early May.


Temperatures likely do not get quite as cold as what we saw Monday again. However, we are still projecting a mostly below normal temperature profile through the end of the month. A couple of moderating days will be in there, but generally, we stay cool. Keep in mind, normal temps are rising, rather rapidly this month, as we pointed out before…but still, we do not see any significant above normal warming coming for at least several more weeks.
