Activity

Weather Day 4:

Make photocopies of the map of North America on the next page. You will be drawing weather symbols on a copy of the map. Pick one of the weather situations described in the para- graphs below (quoted or adapted from reports in the Los Angeles imes) and using the symbols shown on the map’s legend, draw a U.S. weather map for that day. After you’ve done a few of these, those TV and newspaper weather maps should look much more interesting!

“High pressure will promote mostly sunny skies, dry conditions and locally gusty winds across the South- western states today. A few showers, howeve , will dampen the Pacific Northwest, with areas of rain and snow occurring above the central Rocky Mountains. Low pressure, coupled with an associated frontal system, will trigger scattered showers from the eastern Great Lakes to the central Appalachians. Another low south of this storm will set off scattered showers and thunderstorms over the central and southern plains. Partly cloudy skies will continue to cover the Eastern Seaboard.”

Weather Day 1:

Weather Day 5:

“High pressure strengthening over the eastern Pacific will maintain mostly sunny skies along much of the West Coast today. An area of low pressure will curve northward into Canada, creating cloudy skies above the Pacific Northwest. An upper-level disturbance cruising through the Southwest will trigger scattered rain and mountain snow showers, while low pressure developing east of the Rockies produces rain and snow through much of the Plains. Partly cloudy skies will cover the Great Lakes region and most of the Northeast. Thunder- storms will rattle parts of the Southeast.”

“Mostly cloudy skies, light rain showers and higher- elevation snowfall will prevail along the West Coast from Central California northward today as a . . . [low pressure system] pushes in from the eastern Pacific. Skies will become cloudy over the northern Rockies, remaining partly cloudy to the south. High pressure will keep the Plains and the Midwest mostly sunny and warmer as winds become southerly. A few showers may develop in Texas. Mostly sunny skies, windy and cool conditions will continue through the Northeast, while sunny skies and mild weather grace much of the Southeast.”

Weather Day 2:

L.A. Times, November 11, 2001

“Warm and humid air spilling northward from the Gulf of Mexico will combine with a warm front to trigger widely scattered afternoon showers and thunderstorms across the Southeast today. Clouds will linger over western Washington; otherwise, mostly sunny skies and locally breezy conditions will prevail through the West. The Rockies will remain dry, except for a chance of afternoon storms in the southern sections. Sunny, dry weather will continue in the Midwest. A low-pressure system will produce showers and storms from the mid- Atlantic states to the lower Mississippi Valley.”

L.A. Times, July 29, 2001

Weather Day 3:

“A low-pressure system . . . will slide down into the Southeast today, drenching much of the region with locally heavy showers and thunderstorms. The West Coast will continue to bask under sunny skies and seasonable conditions. Late-summer monsoonal moisture will produce partly cloudy skies and isolated afternoon storms over the Rockies and the Southwest. A cold front will advance into the Upper Midwest, triggering scattered showers and storms across the Plains and western Great Lakes. High pressure will promote sunny skies through the Northeast.”

L.A. Times, September 2, 2001

Weather Day 6:

“Low pressure above northeast Canada will swing a cold front over the entire East Coast today, causing rain and cooler conditions along the region, and afternoon snow in western New England. High pressure ridging over the Pacific Northwest will maintain sunny to partly cloudy and seasonable conditions through much of the West. Snow showers may still fall in the north Rockies, while sunny, cool weather prevails in the Plains in the wake of the system that moved into the East. Thunder- storms may erupt in Florida. Jet stream curving south from over western Canada and into Montana. Also, jet stream curving northeast from New Mexico up over New England.”
