Premium Weekly Outlook 5/16 – 5/22: Moderation to around average temperatures late week

After some cooler temperatures today and then some more unsettled weather for Tuesday and Wednesday, moderating temperatures to near normal with pleasant weather returns late this week. But there is a potential fly in the ointment for a warming trend to continue this weekend as a coastal storm may try to develop. For this weekly outlook, we’ll discuss some technical details and thoughts on the weather through this week and this coming weekend.

After a very chilly start with temperatures near record lows across the region, temperatures today should be a little warmer than Sunday’s high temperatures with slightly warmer mid-level temperatures, deep mixing and more sunshine in the afternoon. High temperatures should rise into the lower to middle 60s for much of the region today. A tight pressure gradient and winds around 40kts on top of a deep mixed layer will also cause west-northwest winds to gust between 30mph and 40mph again today. The west-northwest winds will also keep sea-breezes from developing this afternoon for coastal locations.

An occluded frontal boundary will move through region later today, with more showers increasing in coverage this afternoon. Skies will remain mostly cloudy with south to southeast winds, ahead of this boundary and keep temperatures mostly the in the 60s this afternoon.

Heaviest showers are most likely with forcing along the shortwave trough be northwest of the region. Precipitable water values range from 1.50″ to 1.75″. So heavy downpours with localized flooding is possible. Some elevated instability this afternoon with MUCAPE values near 500 J/KG. So there is also chance for some rumbles of thunder.
