Temperatures dipped to between 30°-32° for many central IN neighborhoods this morning. After sunshine and an unseasonably cool afternoon, temperatures will fall to similar levels tonight and Friday morning. As…

A weak weather maker will impact Indiana and the Ohio Valley Thursday, especially during the afternoon into the overnight. Precipitation will be relatively light with most amounts around one tenth of an inch, or less. Note the light precipitation moving through the region Thursday with time stamps below of 7p Thursday and 1a Friday. Wet snow will mix in with the rain over northeastern IN tomorrow night.
A more active week is ahead, with a couple storm systems to track. Note forecast precipitation amounts increase from week 1 to week 2.
Heaviest rains target the lower Ohio Valley and Tennessee Valley week 1 before shifting north week 2. The heavy precipitation axis points a finger from OK and AR through MO and IL, northern IN, and MI week 2.
Some of this heavier rain is just what the Doctor ordered for areas beginning to reflect abnormally dry conditions and/ or drought.
We track a weak, but cold system early next week that could deliver a touch of light wet snow Monday. The GFS led the way on this, but the European and Canadian have jumped on board with today’s runs.
Another (stronger) storm system is in the offing later next week. This should be the one that delivers heavy rains from the mid south on northeast.
Looking ahead towards late month into early April, temperatures will reflect the normal “roller coaster” regime for this time of year; however biased colder than normal. Note the excellent model consensus on the colder than average regime.

After a dry mid week stretch, a Gulf low will transport copious amounts of moisture into the southern Mid West region Friday into Saturday. This will target MO and IL into the Ohio Valley. Locally heavy rainfall can be expected, including amounts up to 2-3″ across southern portions of the aforementioned areas.
The upcoming 7-10 days will feature two additional storms impact the area, including storm number 3 potentially providing wintry precipitation to northern regions as colder air gets back involved with the pattern. No reasons for specifics now, but make a mental note that the pattern will be trending colder in the coming 7-10 day period.
A cold front will deliver light precipitation (rain and snow) to northern regions Monday into Tuesday.
Another, stronger, storm system is due to impact the Mid West next weekend.
Despite the spring “fling” we’ve enjoyed the past couple of days, the pattern is expected to reverse and deliver a return of the cold around, and after, the 20th.
Note the warmer than average conditions continuing tomorrow. Get outside and enjoy!
Models see the cold returning later next week as troughiness returns.
The CFSv2 weeklies see the reversal coming to a colder than normal pattern, as well.
No one should be surprised by the return of the cold pattern. Here’s a look at the median date of the last 32 degree temperature across the region.
Let’s keep a close eye on the Arctic Oscillation (AO) in the coming days. Should it remain negative then the cold pattern may rumble well into April. After a sharp decline mid month, members vary thereafter. We’ll watch carefully.
The latest drought monitor shows abnormally dry conditions across MN, southern WI, southwestern MO, and northern KY. Upcoming 7 day precipitation will help out southern growing areas, but the northern regions remain relatively quiet.
Great Lakes ice coverage remains impressive, to say the least, for mid March at 69% total ice coverage- a byproduct of yet another frigid winter.
Similar to last summer, the abnormal GL ice may help aid in another cooler than normal spring-summer period.
Speaking of the longer range, the latest JAMSTEC shows widespread cool and wet conditions over the Lower 48 for the March, April, and May period.
