Sunshine, a word that we have all used a lot lately, not necessarily because it has been so beautiful outside but because… where is the sunshine? Well, this has been a very dreary and rainy start to May and many factors are attributed to this.
We all know rain in spring is very normal, and so far in May, Elmira, NY (Elmira/Corning Regional Airport) has received 3.18″ of rainfall. The monthly average of rainfall is around 3.11″ showing we are already over the monthly average just 14 days in. Yearly rainfall stats reflect the same, with the year-to-date rainfall totals now at 12.02″ we are almost two inches above the average at this time in the year (10.89″ year to date average).
Temperatures also have been on the chilly side this month. Yes – we have had some anomalous days of warmth in May, but the average so far at this time (as of May 14) is around 63 degrees, about 4 degrees below average for May averages.
Now, why has it been so dreary, chilly and downright bland this month? Well, it is mostly thanks to the placement of something we call the Jet Stream. In basic terms, the Jet Stream acts to separate the cold air from the warm air which also acts as a “highway” for storm systems traveling across the country.
With its current placement just to our south, we are put on the cold side of the jet, allowing below average temperatures. However, it is still close enough where storms systems traveling along it continue to bring cloud cover and rain chances for the Twin Tiers.
Now the question is… will this pattern break? Well… yes and no. The chance for rain looks to continue into late this week and long term guidance keeps that risk – but one thing will change.
The jet will start to creep to our north allowing for a ridge of warm air to move into the region. This will begin on Wednesday, May 15 and the warming trend looks to continue into your weekend and into early next week. Temperatures today are in the 40s, by Wednesday we will be climbing back into the 60s and even low to mid-70s by late this weekend and next week.
Some weather patterns can take weeks and months to break – but mother nature will give us a break eventually, right?
