Meteorologist McCall Vrydaghs takes a look at the Miami Valley winter so far, which has proven to be record breaking.

It’s been a very cold start with record-breaking temperatures into the new year.

In fact, New Year’s Eve tied for the record lowest high temperature at 11 degrees, the same as New Year’s Eve in 1976.

It only got colder for New Year’s Day, which set a record for the lowest high temperature in Dayton, where the high only was 5 degrees. This broke the previous lowest high of 6 degrees in 1928.

Official records show that for January 1, the Dayton International Airport fell to 7 below zero. The record low minimum temperature for January 1 was 8 below zero, which was set back in 1968. This means we started 2018 with the second coldest morning on New Year's Day on record.

Tree pollen staying high this weekend

Meteorologist Kirstie Zontini talks about the pollen counts this weekend.

This time of year if you notice your allergy symptoms, it is likely because of a toss-up between tree pollen or the mold spores, said Storm Center 7 Meteorologist Kirstie Zontini.

WHIO Weather App

Tree pollen is what typically spikes in April and May. Mold spores, during a wet time of year, also can be high. This time of year we can get low amounts of grass pollen in the air as well.

This weekend, sunshine and warm, breezy conditions will allow the tree pollen to climb quickly, while dry weather will allow the mold spores to drop. 

If you suffer from spring allergies, you likely will notice your symptoms this weekend.

The Lyrids peaks this weekend! Meteorologist Kirstie Zontini talks about where and when to look.

Dry and pleasant weather returns just in time for the Lyrid Meteor Shower this weekend, said Storm Center 7 Meteorologist Kirstie Zontini.

The meteor shower peaks before dawn Sunday. The waxing crescent moon will have set around 2:30 a.m. Sunday morning, meaning the sky will be darker to watch for meteors. Grab a blanket and go outside Saturday night/Sunday morning!

The Lyrids usually produce 10 to 20 meteors per hour, but can have outbursts which produce around 100. The radiant point, which is the point where the meteors look to come from of the Lyrid shower, is the constellation Lyra. 

Give yourself 30 minutes outside to let your eyes adjust to the darkness and enjoy the show! You also might see some meteors before dawn on Saturday and Monday.

Could this month be the coldest April on record in the Dayton area?

Published: Friday, April 20, 2018 @ 2:13 PM

Will the month of April shape up to be the coldest on record in the Dayton area?

It’s been a pretty cold month so far, as we’ve had a number of mornings below freezing and snow. 

Data from the National Weather Service backs that up. Records indicate that if the month were to end on April 20, it would in fact be the coldest April on record for the Dayton area.

The coldest April in history occurred in 1950, when the average temperature was just 45 degrees. As of April 20, 2018, the average temperature is 43.2 degrees. That’s almost a whole 2 degrees below the coldest. 

However, that average temperature is certain to rise as we round out the month. We’ll be back in the mid-60s by Monday, and long range models indicate we likely will see highs stay in the 60s for the rest of the month. 

Time will tell how much more that average temperature climbs.
