Forecast for Sunday, May 6, 2012
The cold front that passes through our region has stalled to our south this evening. An area of high pressure has been trying to push in from the north. As it pushes south, it is increasing the onshore flow. So instead of clearing conditions, it has been drawing in moisture from the ocean. This has resulted in clouds and occasional drizzle…especially east. This also has meant a temperature contrast from the shore to the southwestern areas.
Tonight, fog is expected to develop across the area (especially east) with moisture coming in off the ocean and the loss of sunlight. Some of this fog could be locally dense. Some occasional drizzle will continue as well.
The onshore flow is expected to continue Sunday, especially the first half of the day. This means drizzle and fog will be a possibility in the morning. The winds are forecast to turn more southerly later in the day and in return the onshore flow will dissipate. However, a weak cold front approaching from the north could provide cloudiness at the time the clouds may begin to break up from the end of the onshore flow. So expect a mostly cloudy day overall with perhaps a few peaks of sun late. There could be an isolated shower or two in northern areas late in the day with the front.
A weak disturbance may cross the area on Monday with scattered showers and possibly isolated thunderstorms. On Tuesday, a warm front will move through the area. As with any warm front this time of the year, it is possible that it comes to a halt or crawls through the region. Areas close to the boundary will probably be dealing with numerous showers and possibly thunderstorms. A cold front will then close in on the region for Wednesday with another round of showers and thunderstorms. A secondary front will swing through on Thursday with another chance of showers and perhaps a rumble of thunder.
