Here are the weather headlines for mid week:
• The humidity is on the rise through the first half of the week.
• The chance for rain is very low through Tuesday.
• Rain chances increase Wednesday with a cold frontal passage.
• Humidity and temperatures turn lower for the second half of the week.
Southwest winds keep drawing in warmer and more humid air into the Southern Tier. Temperatures made it into the upper 80s Monday and we should flirt with 90 Tuesday.
It may be hot and humid Tuesday, but there won’t be much of a trigger in the atmosphere (say a front or jet stream disturbance) to get thunderstorms to pop. Most, if not all, of us will remain dry Tuesday.
A cold front will track east across the area Wednesday. That front will go to work on the very warm and humid air mass and showers and storms will be the result. In fact, our best chance for rain this week appears to be Wednesday. It looks like the front will move through the region a bit faster than we were thinking earlier and that is why we’ve lowered Wednesday high just a bit.
That same cold front will help sweep the heat and humidity out and you can expect cooler, less humid and dry weather for the end of the week.
