Will Spring Weather Continue?

Another Spectacular Spring Day for Monday!

Our warming trend will continue today with sunshine and high temperatures in the upper teens away from Lake Ontario. However, temperatures will be a few degrees cooler near the lake with a light east wind.

Tuesday will be a pleasant spring day, but clouds will increase through the day. If the clouds thicken more quickly than currently expected, our temperatures will come up short of current forecast numbers. In addition, a south wind off Lake Ontario will keep temperatures several degrees cooler along the north shore of the lake. Showers will develop during the evening.

Cooler & Unsettled Mid-Week

Our next system will bring rain and cooler temperatures to our region Tuesday night and Wednesday, but at least the precipitation will be liquid, not snow or ice! There is a lot of uncertainty regarding how quickly the system exits our region, but at this point we think the most likely scenario keeps showers lingering into Thursday and temperatures will remain cooler than normal.

Pleasant Friday; Cooler for the Weekend

Friday looks be a plesant spring day with some sunshine and temperatures reaching the mid to upper teens. However, we will be watching the timing of an approaching cold front - faster timing would jeopardize Friday afternoon's weather. This front will bring a period of showers Friday evening. 

Saturday will be a rather chilly day - feeling more like early April with a gusty northwest wind and a passing shower possible. However, sunshine will return during the weekend and temperatures on Sunday will be a few degrees milder. 

A Few Days of Warmth Next Week?

It is still early, but confidence is increasing that we will have a significant warm-up during the beginning and middle of next week. The warm-up would most likely be temporary but it would bring the potential for a couple days of 20+ degree temperatures as we start the month of May. 

Long Range Discussion - Late April, May & into June

The first two weeks of May will bring back and forth swings in temperature, including some rather warm weather during the first couple days of the month followed by a period of cooler weather as we will continue to struggle to have any persistent warmth. 

For mid and late May the signals are mixed. We have been expecting a pattern reversal to a warmer than normal pattern, and that could still occur. However, at this point it looks like near normal temperatures are more likely. Keep in mind that during mid-May seasonal is in the upper teens, so this still a much warmer pattern than we saw during the first three weeks of April. 

Our confidence in the pattern for June is actually higher than it is for May. At this point it looks like June will be a rather warm month (warmer than normal) across the region. A delayed start to spring does not mean a delayed start to summer - it looks like we could feel summer-like heat earlier than normal this year.
