Radar Down

Hurricane Maria passed through Puerto Rico causing significant wind and flooding damage across much of the island. Winds in excess of 100 mph destroyed the National Weather Service Radar at San Juan, Puerto Rico. The radar is expected to be down for at least a few months. Hopefully there will not be any storms in this area anytime soon. Here is a look at what the radar looks like after the hurricane.

Here is a where the radar is positioned on the island.

A closer shot of the location.

 

Here is a map to show how much rain fall on the island.

Record Breaking Heat

It was a record breaking weekend as far as the warm temperatures went across portions of eastern Iowa.  Record high temperatures were broken both Saturday and Sunday. (September 23rd and 24th).

Record highs will not be in jeopardy Monday, but it will still be much warmer than average.  More fall-like temperatures are forecast by the middle of the work week.

More Hot Temperatures

Happy fall.  Don’t tell that to Mother Nature, though.  We are in store for another hot weekend with temperatures in the upper 80s to near 90°. These will be very close to record territory once again on Saturday.

After this weekend, a slow moving cold front will track through the area Monday and Tuesday, which will provide scattered rain and storms, and behind the front there will be cooler temperatures.  Here’s the Climate Prediction Center’s outlook for September 28th through October 2nd, showing a good chance at near normal to below normal temperatures.

Speaking of fall, you may be curious about the peak of the leaves changing colors.  We got an early start this year in portions of eastern Iowa due to the dry conditions.  But, normally it usually peaks around the middle of October.

Near Record Highs Friday

We are ending the summer on a HOT note, with high temperatures in the 80s and 90s across eastern Iowa over the last few days.  In fact, Cedar Rapids tied the record high for September 21st at 93°, which was last reached on this date in 1920.  The Autumnal Equinox is at 3:02 PM Friday.  However, it’s going to still feel like we are in the middle of summer.  High temperatures will be very close to record for September 22nd.

There seems to be a better chance at tomorrow being the warmest start to Fall ever across eastern Iowa.  Keep in mind, each year the Autumnal Equinox may vary between September 22nd or September 23rd.

However, if you are one of those people ready for fall-like weather, we don’t have to wait too long.  The long-term trends point to cooler temperatures by the middle of next week, and at or below normal temperatures as we head into the first week of October.  This is from the Climate Prediction Center.
