WEATHER BLOG: Sunday

—As of early this morning, upper low pressure continues to spiral over the Great Lakes. The heaviest rains associated with the system have fallen across coastal southern NJ and are now moving northward into New England

—A dry slot of air is moving into the Mid-Atlantic this morning and will continue to track eastward throughout the day — this will lead to some breaks in the clouds later this morning, making for a decent Sunday in many places

—Upper low pressure will move from New England into southern Canada tomorrow, as ridging briefly builds into the area; a persistently trough-dominated pattern may mean that Monday is the weather "pick of the week" for many locations

—Tuesday, a sharp upper trough across the Great Lakes will be the cause of atmospheric ascent and numerous showers and storms from Pennsylvania into New York… we think that some of the storms could be heavy and the risk for localized flooding exists. The ECMWF ensemble mean indicates that eastern PA into northern Maryland will be the
"hot spot" for storms.

—Expect a noticeable increase in humidity on Tuesday

—Wednesday, thunderstorm coverage will be reduced but not eliminated as the upper trough swings through — it will also be rather humid

—Yet another trough will move into the Ohio Valley on Thursday… the question is, how far east will it cause showers/storms? Currently, we coved from the Appalachians on westward, though recent modeling is more aggressive with eastern extent

—Friday into next weekend, we'll be stuck in a broad southwesterly flow upper regime — this means that it will be rather humid as upper disturbances frequently round a trough that will be centered over the Great Lakes.

—Temperatures through the period will average near normal… with highs slightly below normal and lows generally above normal

Have a good day!
