Weather Underground Forecast for Monday, November 16, 2009.
The mid-section of the nation will start the work-week with a bit of active weather on Monday as a storm system in the Southern Plains moves into the Mid-Mississippi Valley. The system will remain situated over the Mid-Mississippi Valley throughout much of the day while it's associated frontal boundary extends southward to the Gulf Coast. Moisture from the Gulf of Mexico will interact with this front to produce numerous showers and isolated thunderstorms through the day. The heaviest amounts of precipitation are expected near the Gulf Coast. Persistent rainfall may yield to areas of local flooding near streams and rivers. Meanwhile, flow around this system will also produce rain showers in the Ohio Valley and snow showers in the eastern areas of the Central Plains. Expect travel difficulties due to snowfall in the eastern regions of Nebraska and Kansas.
In the West, light to moderate rainfall and high elevation snowfall will persist in the Pacific Northwest as another front approaches the coast. Fair and dry weather will remain over California and the Central Great Basin due to a lingering ridge of high pressure. Offshore flow associated with this ridge will translate into warmer temperatures and strong winds in southern California.
Elsewhere, tranquil weather conditions will persist in the eastern third of the nation due to high pressure.
Temperatures in the Lower 48 states Sunday ranged from a low of -7 degrees at Lake Yellowstone, Wyo. to a high of 89 degrees at Laredo, Texas.
Hurricane warnings were in effect for Puerto Rico and the Virgin Islands on this date in 1999 as Hurricane Lenny threatened the islands. Lenny packed winds of 115 mph and was not only unusual because it was so late in the season. It was also unusual because it moved west to east across the Caribbean, making it the first hurricane to approach Puerto Rico from the west.
