July 1930 was one of the hottest and driest summers in the U.S., particularly in the Missouri Valley where severe drought conditions developed. Toward the end of the month state records were set for Kentucky with 114 degrees, and Mississippi with 115 degrees.

Burt) 1953 - Twenty-two inches of hail reportedly fell northeast of Dickinson, ND. (The Weather Channel) 1975: Annandale, Fairfax County, VA 16 people were struck and injured while picnicking. (Ref.

(The Weather Channel) 1987 - Thunderstorms produced severe weather across Minnesota, Wisconsin and Michigan. Thunderstorms produced wind gusts to 87 mph at Mosinee, WI, and strong thunderstorm winds capsized twenty-six boats on Grand Traverse Bay drowning two women. Thunderstorms produced nine inches of rain at Shakopee, MN, with 7.83 inches reported in six hours at Chaska, MN.

Showers and thunderstorms produced much needed rains from New England to southern Texas. Salem, IN, was deluged with 7.2 inches of rain resulting in flash flooding. (The National Weather Summary) 1989 - Showers and thunderstorms in the Middle Atlantic Coast Region soaked Wilmington, DE, with 2.28 inches of rain, pushing their total for the period May through July past the previous record of 22.43 inches. Heavy rain over that three month period virtually wiped out a 16.82 inch deficit which had been building since drought conditions began in 1985.

SnowGoose69 Posted July 20 Share Posted July 20 2 hours ago, NEG NAO said: Seems like Upton is discounting the widespread regional flood threat for tomorrow and Wednesday. Thoughts ? AFD from KOKX Alot depends on how the whole thing evolves. If the late AM/early aftn wave is more significant the evening won't be as bad. Thats evident on most of the high res models too. HRRR has a stronger early wave, high res GFS/RRFS have mostly just a late one. Instability looks more impressive in the evening than the Saturday event and less in the early wave/warm front than Saturday. 1 Link to comment Share on other sites More sharing options...

I think we've already seen the worst of the heat. Unlike those years, we've had heat early and often, with 80s as early as March, 90s as early as April, and 100+ earlier this month. I highly doubt we see more 90-degree days in August than in June or July. 4 Link to comment Share on other sites More sharing options...

donsutherland1 Posted July 20 Share Posted July 20 A cooler regime is in place and will remain in place for an extended period of time. Highs will generally reach the upper 70s and lower 80s through the week and into the start of the weekend. Showers and thunderstorms are likely tomorrow into Wednesday. Some areas could pick up heavy downpours with flooding a possibility. Daily rainfall records for July 21 include: Atlantic City: 4.60", 1969 Bridgeport: 2.16", 1961 Islip: 2.69", 1984 New York City-Central Park: 2.26", 1983 New York City-JFK Airport: 2.45", 1948 New York City-LaGuardia Airport: 2.06", 2006 Newark: 3.23", 2006 Philadelphia: 3.45", 1988 Wilmington, DE: 3.80"m, 1988 The long-term outlook for the remainder of July has swung to near normal or even somewhat cooler than normal on the guidance. The ENSO Region 1+2 anomaly was +3.6°C and the Region 3.4 anomaly was +2.1°C for the week centered around July 15. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +3.20°C and the ENSO Region 3.4 anomaly has averaged +1.82°C. The ongoing strong El Niño will continue to strengthen through the summer. The SOI was -21.79 today. The preliminary Arctic Oscillation (AO) was -0.825 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 64% probability that New York City will have a cooler than normal July (1991-2020 normal). July will likely finish with a mean temperature near 76.8° (0.7° below normal). Supplemental Information: The projected mean would be 0.3° above the 1981-2010 normal monthly value. 1 Link to comment Share on other sites More sharing options...
