Keeping on track

01 Jun 2011 05:58 AM
May is now in the books and for growing degree days totals, it was about on average for May. A warm stretch during the second week of the month really helped to warm up the soils and get the crops going for hopefully a good growing season. June is now here and so is the heat with highs expected in the 80s to near 90 for the rest of the week.

Summer starts muggy

30 May 2011 05:56 AM
The unofficial start to summer is today and the summer-like muggy air has returned just in time. The featured chart presents dew point observations so far this month and the spike upwards yesterday was thanks to a warm front that made it into Iowa late Sunday afternoon. Dew point readings were the warmest since the second week of May.

Lack of SW winds continues

19 May 2011 07:35 AM
Our winds are again out of the east this morning with an approaching storm system to our west. These winds are not as warm as those from our southwest. The featured chart presents the number of unique hours during which a wind observation of at least 5 knots was reported by the Des Moines ASOS since the first of April. Since 1973, this calculation would indicate that this year has seen the fewest number of hours.

Much cooler weekend

13 May 2011 06:01 AM
This week has seen very warm weather for early march with highs topping out on Tuesday in the lower 90s for Ames. Much cooler air has arrived just in time for the weekend thanks to a passing storm system. The featured chart shows our hourly temperatures for this week and a forecast from one of the government models called GFS. It looks like we are back in the regime of struggling to reach 60, but warmer weather is set to return next week along with some sunshine.

Colder than April

04 May 2011 07:17 AM
Iowa is experiencing another chilly May morning with lows in the 20s and 30s. For some locations, the lows experienced over the past two days have been colder than the coldest daily low temperature in April. This situation is very rare and has only happened during a couple of years since 1893. The featured plot compares the coldest temperature in May against April. A negative value would mean the May lowest temperature was colder than April. Warmer weather is set to return today, but with it will come chances of rain!
