A warming trend will begin tonight with the return of a southeast breeze, so look for 50s tonight, 70s tomorrow, then right back in the 80s by mid-week. That's all a bit of a diversion from the original question, though, and isn't directly related to wind chill. today with the 'vernal equinox' taking place, but it will still feel a but like winter today with temps running 15 degrees below average. As another example, if the air was saturated so that its relative humidity was already 100% or very close, then regardless of how strong the wind was there would be no net evaporation from the water surface and the water would not cool down. KCCI 8 News is your weather source for the latest forecast, radar, alerts, closings and video forecast. What happened from that point would depend on the source of the air, how it came to be 36 degrees in the first place, how much water is involved and what sort of container it is in, and so on. This would occur more rapidly the higher the wind speed was, but involves a lot of complexities - for example, if the air remains at 36 degrees and the water cools due to evaporation, heat will be transferred into the water from the air, which would warm the water and cool (plus humidify) the air. All this means that the wind chill value of 27 degrees is a nearly meaningless number from the point of view of the water or any other inanimate material that doesn't have an internal heat source.Īs an aside, one could probably postulate a scenario in which evaporation of the water, the rate of which would depend in part on the humidity of the air and on the wind speed, could cool the water enough to reach the freezing point. After a chilly day on Sunday for Southie’s St. Remember that for a person, the 36 degree air is blowing across skin that will try to maintain itself at a temperature of around 90 degrees or a little higher, so that there is a strong transfer of heat from the skin into the air. In one of the biggest shockers in Boston weather recorded history, the first week of spring is actually going to feel like spring. Currently, minor flooding is possible Thursday night and Friday. If the temperature of the air and water is 36 degrees for both, air blowing across the water will not transfer heat out of or into the water because they are the same temperature to begin with. Louis is in the zone expected to see around 2 of rainfall, with the axis of the heaviest rain (3 +) focused south of I-44. Water, on the other hand, does not produce any heat on its own, so there is no wind chill effect.
