Notes: Our main radar server is having technical issues; we
hope to get it back up this afternoon. In the interim, some imagery is 
available at http://weather.admin.niu.edu/radar . Thanks for your
patience!

Also, I'll be out of the office on Monday, Memorial Day.
During that time, a National Weather Service forecast will
be sent via email and on our website.

The average high/low temperature is 73/50. We have had no rainfall
equivalent at the DeKalb campus over the last 24 hours ending at 7 AM
this morning. Forecast was for 57/37 and a light frost.

We have had 1.89" of rainfall equivalent this month. On average,
we should see 4.55" of rainfall equivalent by May 31.
We have had 18.16" of rainfall equivalent so far this year.
By May 31, our average annual liquid total should be 13.09".
****************************************************************************
SEVERE/HAZARDOUS WEATHER OUTLOOK: Thunderstorms are possible on
Monday (Memorial Day), and also on Tuesday as a slow-moving
warm front approaches and then plods through the area.
There is at least a chance of gusty winds and some hail with some of
these thunderstorms, especially around Tuesday. After that,
more thunderstorms are expected late next week, around Thursday
and/or Friday.
*****************************************************************************
PRECIPITATION: Sunday: .01"-.33", and 50% coverage.
****************************************************************************
FORECAST DISCUSSION: As expected, today we have a nice, sunny day...albeit
cool. Unfortunately, today and tomorrow will be the nicest of the next
5 days as the long-advertised warm front slowly approaches us this weekend, 
producing almost continual lift, clouds, and periodic showers
and thunderstorms. Although I kept Saturday dry, the compromise I went
with yesterday may be a bit too aggressive, and I have now included all of 
Sunday as having a chance of rain. The instability increases as warmer air 
comes in aloft on Memorial Day, and then we throw the chance of thunderstorms 
into the mix as well. Those chances may increase on
Tuesday as the warm front moves through, and then Wednesday and Thursday look 
warm and fairly humid, with thunderstorm chances increasing
again as the cold front approaches at that time.

Due to the ongoing computer issue, that's all I have time for today.
Again: on Memorial Day: If you have any outdoor plans, it won't be
raining all day, not by a long shot, but plan on a period or two of
indoor time due to thunderstorms. Lightning is dangerous, and it
must be respected at all times!

Have a great weekend, and thanks to all who served in our country,
and paid the price of their life so we could be free.
