A Cool Week – Freeze Warning

Bill's Blog

The high temperature Tuesday of 40° in Grand Rapids was 20° colder than average. So far (thru Tue.) the month of April is still averaging 2.8° warmer than average. We’ve now had 8 days in a row with cooler than average temperatures, coming right after a stretch of 10 days that were warmer than average. The average high temperature for today (Wed.) is 60°. We’ll be in the mid 40’s this afternoon, about 15° below average. Temperatures will reach the low 50s Thursday PM and near 60° Friday afternoon. I can see us hitting 70° again during the middle of next week.

The temperature in Grand Rapids rose from 47° at midnight to 51° at 2 am Mon., then back to 47° at 3 am. Kalamazoo had a temp. of 56° at noon Monday. Then the cold front passed through and the temperature fell to 43° by 2 pm. The temperature dropped 13° when the sun was highest in the sky. Here’s radar:

Snowfall map from the Weather Prediction Center

I can’t think of the last time a snowstorm passed south of Grand Rapids on April 20th. You can see quite an arc of snowfall from Montana to Colorado – east to Illinois and then northeast into Canada. There’s another area of significant snow north of Lake Superior. Painesdale in Upper Michigan had 5″ of snow on Monday.

Grand Rapids NWS Graphic…cold, but not much or not any snow for much of the area.
Temperature Departure from Average next 5 days

This map shows temperature departure from average over the next 5 days. Quite a contrast…it’s summer on the West Coast and we’re back to March in most areas east of the Rockies (S. Florida stays warm).

Expected rainfall across Florida

Central Florida gets soaked over the next 3 days…over 4″ possible near Orlando.
