ITHACA, N.Y. — It will be quiet and seasonable for the next few days, but now is the time to stock up on ice, beverages, and anything else you’ll need to get through the near-triple digit heat due to arrive by the weekend.

With the exception of last Monday’s heat advisory, the weather last week was fairly quiet and a pleasant start to the beginning of astronomical summer. Temperatures for the month of June so far are just a hair below average, while this past weekend’s half inch of rain helped but a dent into the precipitation deficit we’ve been experiencing over the past few months (could still use some more, however).
On the topic of heat advisories, we’ll be keeping a close eye on a major surge of hot air (no, not from Washington D.C.) that will be invading the region by the end of the work week. In the short term, however, things are looking good.
Your Weekly Weather
The center of low pressure that brought this weekend’s rain is now off the Canadian Atlantic Coast, and with its departure, high pressure is moving in from the northwest. This will help clear out the skies from any lingering cloud masses, and its clockwise flow will channel some mild but drier air for the next day or so, the humidity will be noticeably low for the first half of the week.
For your Monday, expect mostly cloudy skies to clear out and become mostly clear with maybe just a few stragglers by the evening hours. Temperatures will be a bit below normal but still pleasant, with highs in the lower 70s in the more rural and elevated areas, mid 70s in Ithaca proper. For Monday night, temperatures will cool off rapidly with the dry air, light wind and clear skies overhead, and if you’re out late, you’ll want a jacket as temperatures drop as low as the mid 40s.
Tuesday will see a shift in the winds from the northwest, to the east and then the southeast as the high treks eastward to the north of us. As a result, we’ll start to tap into some milder and somewhat moister air, although it should still be fairly comfortable. Tuesday will host partly cloudy skies with highs around 80 °F. The next frontal boundary begins to make its way in Tuesday night, so expect increasing clouds after sunset Tuesday, with lows only falling back to the upper 50s to around 60.
Wednesday will be wet and unsettled as showers and thunderstorms pass through the region. Heavy rain may be possible at times, though severe weather seems to be a question mark – the upper air dynamics are favorable, but the frontal boundary itself won’t arrive until during the night when there’s less energy in the atmosphere. For now, prepare for downpours and if anything worse comes up, we’ll keep you posted. Highs Wednesday will be around 80 °F. Wednesday night will be warm and wet, periods of rain and thunderstorms possible with lows only in the upper 60s.
By Thursday morning, the intense heat dome over the central United States will begin pressing into the region on the tail end of the storm system. It will be muggy and it will be warm, with partly cloudy skies and highs in the mid 80s, maybe a few degrees cooler on the hilltops. Showers and storms will decrease in coverage as the day progresses and the air mass of high pressure builds in. Thursday night will have decreasing clouds and lows in the mid 60s.
Friday will be hot and muggy, with highs near 90 °F. Saturday is expected to be even hotter, muggy and in the mid 90s, with a heat index into the 100s possible. Sunday will also be in the mid 90s, and upper 90s to near 100 °F for the actual temperature is a possibility. With these hot and humid conditions, heat advisories may be issued.
Hope you all enjoy a nice roast for the fourth of July. The heat that will be arriving late this week is expected to persist well into the following week as the ridge of hot air remains firmly entrenched aloft, and the unseasonably high heat may persist into mid month according to some of the mid-range models. While it may not be as hot as Saturday and Sunday, the heat is on.
