In my last blog I mentioned that in one way our early stretch of June rainy weather was not all that different from some previous Junes - 2012 and 2010. We’ve had similar number of days with rain this June so far (10 days) compared to last June (9), for example. However, I got to thinking whether it is it really fair to make that comparison.
Normally by the time you get to June, central New York’s rainfall tends to be more scattered in nature. Showers and thunderstorms bubble up and we get wet for a couple of hours and that is it during a given day. Around those showers and storms it is fairly typical to have some sunshine and dry weather which allows you to get outside to do work or just enjoy central New York.
However, this June has been a bit different. We’ve had several days already this month where steady rain has fallen during much of the daylight as out-of-season low pressure systems impacted central New York. With that as a background I decided to look at the number of HOURS it has rained this June compared to last June. Here are the numbers.
Days with Rain
Total Hours of Rain
Days with at least
8 Hour of Rain
There is a big difference in the total hours. There has 64% more time with rain so far this June compared to last June. It may feel like it has been raining all month but even with the wetter than normal weather (we’ve had almost 5 inches) it has rained ‘only’ 20% of the time this month. I don’t know how these numbers compare to normal.
A noticeable change in the pattern over the East is taking places and that will allow for us to see an extended period of dry weather for central New York. After Friday, we transition into a summery pattern for 4 or 5 days. That seems appropriate since Summer officially arrives early in the morning on Friday. One of the reasons for the wet pattern for much of the first 2 weeks plus of June has been a persistent trough of low pressure here in the East. Now the jet stream is about to shift decidedly to the north.
This will push our temperatures well into the 80s with at least a couple of chances for us to crack 90 degrees (most likely Monday and Tuesday) If that were to happen, we would already be at four 90 degree days for the season, about half of what we normally see during the warm season. Not bad for a summer season that has overall started out on the cool side.
