Upcoming wind and weather prediction for birds

Nothing much has been reported of late cause winds were mostly north which presents migratory resistance. But that's about to change for the upcoming weekend into Monday with southerly warm winds which is what the spring migrating birds want. For your information from the National Weather Service:

Saturday Night: A chance of showers. Cloudy, with a low around 52. Southwest wind between 8 and 14 mph. Chance of precipitation is 40%.


Sunday: A slight chance of showers before noon. Mostly cloudy, with a high near 76. Chance of precipitation is 20%.


Sunday Night: Partly cloudy, with a low around 60.


Monday: Mostly sunny, with a high near 80.

BirdCast Migration Forecast: 6 - 12 April 2012
After an amazingly early start to spring migration across much of the eastern two-thirds of North America, we expect migration to return to a more typical schedule this week. Arrival dates should be only slightly ahead of average through the remainder of this week. The period will start with high pressure across much of the U.S.. This high will weaken as a storm system develops off the New England coast and tracks to southeastern Canada where it will take up residence through Wednesday. This slow moving system will combine with a large Canadian high pressure system and bring northerly winds across much of the eastern U.S through until late in the forecast period. The period will begin quiet on the West Coast until another storm hits Monday. This storm will track into the northern Plains by Friday. Southerly winds will develop ahead of it for the central U.S as high pressure covers the east Thursday and Friday. Generally unsettled weather conditions will prevail along the west coast much of the period after the weekend.
