A sprawling high pressure system centered over Maine for the next few days makes for a straightforward forecast. Look for mostly sunny, dry, and mild weather from now through Friday. Today's high will be in the upper 60s while tomorrow and Friday should warm to the mid 70s.
Mild weather has been the rule for quite some time now. Last month's average temperature of 71.8 degrees tied 1884 and 1983 as the tenth warmest September in Central Park since observations began in 1869. The first nine months of this year are tied with 2002 as the fourth warmest January-September on record. Finally, when compared to the standard 1981-2010 average, September was the 15th consecutive month with warmer than normal temperatures, the longest such streak on record.
It looks like we may have unsettled weather this weekend, not because of Hurricane Matthew, but from a boring old cold front that is expected to arrive Saturday night. The front may bring some rain and cooler weather, with Sunday's high only reaching the mid 60s.
Hurricane Matthew hit Haiti yesterday with 145 mph winds and torrential rain, causing an as yet unknown amount of destruction across the southwestern portion of the country. The storm is now regaining strength as it passes over the Bahamas and heads toward Florida.
The current forecast has the storm slowly paralleling the Atlantic coast from southern Florida up to North Carolina. If the storm takes that route the big threat will be the storm surge, as northeasterly winds push ocean waters onshore. Matthew is expected to be near Cape Hatteras by Monday morning, its northward movement being held in check by strong westerly upper-level winds.
