With high pressure centered over Ohio, today's weather will be awfully nice. Look for clear skies and a high in the low to mid 80s. Saturday should start out dry but the approach and passage of a warm front late in the day will increase the humidity and give us a slight chance of showers tomorrow evening. Those showers will mainly stay west of the city but we may see one or two of them wander over the Hudson. Tomorrow will probably be a degree or two warmer than today.

All this week we've been entertained by a shortwave disturbance in the jet stream as it makes its way from the Pacific across the continent. The disturbance is over Alberta this morning but will dip into the Great Lakes tomorrow and up the East Coast on Sunday. In doing so it will bring us a good chance for showers and thunderstorms on Sunday into Monday. Both days will be pretty warm and sticky, but in the wake of that shortwave much of next week is shaping up to be dry and on the cool side, with highs only reaching 80 degrees or so.

The basis for any weather forecast is good observations. Satellites, radar, automated instruments are essential, but the National Weather Service also relies on over 8,500 volunteer observers across the country who take daily measurements of temperature, precipitation, cloud cover, winds, etc. Those observations provide the input for forecasts and the data to judge how well those forecasts turned out. No volunteer observer has performed this duty longer than Bridgehampton farmer Richard G. Hendrickson. Mr. Hendrickson began taking observations in August 1930 and hasn't stopped since. Eight-four years! On Sunday the National Weather Service will honor Mr. Hendrickson's service and name their 80 year service award after him. Gothamist thanks him for his service with today's graph of the 60,000+ daily high and low temperatures Mr. Hendrickson has observed.
