Heat Advisories Again Today
Hot and muggy weather will continue in the Finger Lakes for a few more days.
Today will end up being one of the hotter, if not the hottest, day of the week.
There will be nothing in the atmosphere today to trigger showers and thunderstorms. Without these, or even the large cumulus clouds, the heat will be allowed to build uninterrupted. If anything does pop-up, it will most likely do so near the Pennsylvania state line.
Mid 90s for highs should be expected in the general vicinity of I-90, with widespread low 90s throughout the Finger Lakes region.
Dewpoints will remain in the low and mid 60s, keeping heat index values close to the actual temperatures. Winds will be from the south, but under 5 mph.
Overnight lows will be in the low and mid 70s for much of the region, getting us off to a fast start on Friday. Highs will again reach the low and mid 90s, but the chances for rain will increase again.
Friday’s thunderstorm activity will be most common in the western and northern halves of the region. However, there is some uncertainty in this indirectly tied to the path of what could become Tropical Storm Fay today.
Unsettled Weekend Weather
Rain from Fay will lift north into New England Friday night into Saturday. Some models present an alternate scenario where the rain comes further west, but still stays mostly east of I-81. I favor the more eastern, New England scenarios.
Behind Fay, an area of low pressure will track through the Great Lakes and across our region. This should arrive later Saturday with scattered showers and thunderstorms, but not before one final day near 90 degrees.
Rain will spread slowly from west to east during the afternoon and into the evening hours Saturday. A few showers will linger behind on Sunday, but these should be much less numerous. High temperatures on Sunday will retreat to the low 80s.
Rain amounts should be beneficial, but not excessive. Many areas should see around or over a half-inch with a few locally higher amounts.
Scattered showers and storms will again roll through on Monday. This rain will probably be less widespread than Saturday’s rain. Temperatures will remain in the 80s, or even top out in the upper 70s.
Tuesday should be quieter with highs in the low 80s. Then, it is back to the heat for Wednesday and Thursday, at least. Thursday in particular looks very hot once again.
