We are still accepting applications for a summer intern! The deadline is fast approaching next Monday, March 2 at 8AM. Link to the full PDF description here ➡️https://mrcc.purdue.edu/files/staff/2026MRCCSummerIntern.pdf

Has it felt dry this winter? You're not imagining it. So far this winter (Dec. 1-Present), it is the driest or near-driest winter in many locations. These precipitation totals take into account both rain and snow. The rain part has been very lacking this winter.

Hopefully everyone has a great Valentine's Day this weekend!

How severe is this winter where you are? Many eastern locations are seeing a severe or extreme winter, while many western locations are seeing their WARMEST winter on record (so far).

Please note our website is down today due to planned campus-wide server maintenance. We apologize for the inconvenience.

At the MRCC, we love interns--and we're excited to announce we're accepting applications for a 2026 summer intern! It's a paid, full-time internship that runs from May through August. Must be availbale at least 9 of the 12 weeks. More details here ➡️https://mrcc.purdue.edu/about/join-our-team

So, it's still really dry across Illinois. January brought snow, but not so much precipitation to give us some relief. To give some idea of how dry it's been since August... the last 6 months is the 5th driest of any 6 month period on record in Bloomington-Normal, with only 7.10".

While this storm did cause an uptick in locations observing severe or even extreme winters in the east, the big AWSSI story remains out west where many stations are observing their warmest winter on record. AWSSI ➡️ mrcc.purdue.edu/research/awssi
