Afternoon temps nearly 20 degrees below normal today, but no snow...in fact, just a few sprinkles. The heavier precip never broke through enough to get any measurable precip, let alone changing to snow during steadier rates. So DTWs last snow of the 2011-12 season looks to have been a T on April 11th. Still have that wintry nip in the air enroute to a freeze tonight.

Through today the 28th. St. Louis is running at 60.1F and (3.2F+) above normal for April versus the 1981-2010 Climo.

The next two days are forecast to be slightly above normal.

So April is looking to finish 3.5F above normal or so.

St. Louis, Missouri

Period of record: 1874- Present

Top Ten Avg. Temperatures

1) 49.9 2012

2) 48.1 1921

3) 47.6 1878

4) 47.3 1946

5) 47.0 1990/1880

7) 46.2 2006

8) 46.1 1992/1925

10) 46.0 1938

March really messed things up. It was so absurd that it will be very hard for cold anomalies to prevent a new yearly record or top 5 event.

To start with the record Spring temperature average here is 61.5F. Yeah, that's it. 61.5F. Well, March was 61.1F and April is going to finish about 60.5F. So going into the last month of Spring on the record books. We will be sitting at 60.7 or 60.8F.

The average May in STL is 67F.

The month is forecated to start 10-12F above normal per day the first week

If May finishes at 70F then the Spring will finish at 64F. If it finishes at 65F then it will finish at 62.3F. In order for Spring to not set a new record May would have to finish at 62.8F or below. that is not going to happen. So now it is a question of how much.

For the entire year the record is 60.1F. That is in danger at this point of being destroyed.

Interesting, someone from Indiana was just mentioning the other day that they were +1.5 for the month of April. This was before the past few days of below normal departures too.

Nice that your getting more sun! The current observation for UGN is goofed up - I would say it is 80% cloudy here and has been that way for awhile.

April looks to end up right near the mark and thus normal around here.

Looks like we're about to get in on some moderate rain. The 18z GFS is terrible even in the short term. It shows two areas of decent rain, with Milwaukee getting barely anything in the middle with this little system, and I can already tell that will be wrong. If it can't even verify 12 hours out, it's hard to take anything it shows beyond that seriously.
