| Heavy rain in South; potent NW storm to widen
October 26, 2009
South
Locally heavy rain is possible in the Ark-La-Tex region today ahead of an approaching cold front and upper level trough. This rain will be falling over saturated ground from recent rainfall, and with rivers already near or in flood is expected to produce additional flooding. An area of low pressure is forecast to develop in the northern Gulf of Mexico tonight and tomorrow and head northward through the Mid-South: combined with the upper trough, this will lead to more heavy rain from the Lower Mississippi Valley across the Southeast tomorrow and to the Mid-Atlantic Coast by Wednesday. Along the Southeast Coast, an area of low pressure is forecast to move up the coast today and tomorrow, bringing a chance of rain from the Florida Peninsula to Virginia. Another storm system will move into the Plains later this week bringing another round of rain, wind, and cooler temperatures. Highs today will range from the low 50s in portions of North Texas to near 90 in southeast Florida.
West
A potent storm system that will impact much of the country this week is moving into the Pacific Northwest today, bringing locally heavy rain and mountain snow to the Pacific Northwest. As the system moves inland, snow levels will drop to valley floors in some locations. Rain and snow are expected over the Pacific Northwest, Northern Rockies and High Plains, and northern sections of the Great Basin tomorrow, with snow spreading throughout the Rockies and High Plains by Wednesday. Gusty winds are also expected to spread across the region as this system moves inland. Another system will move into the Pacific Northwest late in the week bringing more rain and mountain snow. Cool to cold temperatures will also spread across the region this week, with afternoon highs as much as 30 degrees below average by Wednesday and Thursday. Highs today will range from the 20s near Glacier National Park to the upper 80s in the Lower Colorado Valley.
Midwest
Showery weather is expected to stretch from the Great Lakes to the Ozarks today and tonight near a slow moving frontal boundary. As an area of low pressure moves northward into the Ohio Valley tomorrow, rain chances will increase from the Mid-Mississippi Valley through the Ohio Valley to the Great Lakes Tuesday and Wednesday. A strong system moving out of the West will bring rain and wind to the Plains and Mississippi Valley, along with some snow to portions of the Plains. Much colder temperatures are also expected with this system. Highs today will range from around 40 near Lake Superior to near 70 in the Lower Ohio Valley.
Northeast
A dry day is expected across the Northeast with temperatures generally near seasonal averages. Some light rain, snow, or a wintry mix is possible tonight into tomorrow in northern New York and Northern New England. Showers will also begin to move northward into the Mid-Atlantic tomorrow as an area of low pressure moves up the East Coast and out to sea, while rain will spread in from the west tomorrow night and Wednesday. Dry weather is expected late week, with more rain by the weekend. Highs today will range from near 40 in northern Maine to the upper 60s in western West Virginia.
In The Tropics
CENTRAL PACIFIC
Tropical Storm Neki, northwest of Hawaii with 40 mile per hour winds (as of 11:00 pm Hawaii time Sunday), has had lopsided convection all day Sunday. The storms have been persistent, but displaced to the northeast side of the center. Additionally, Neki meandered early Sunday, but has now begun to move to the north. The forecast track is for Neki to accelerate to the north-northeast slowly weaken. The storm is expected to become extratropical by early Tuesday.
WESTERN PACIFIC
In the western Pacific, a new tropical depression (23-W) formed east of Guam Sunday evening (Eastern time). It is forecast to become a tropical storm later today, come close to Guam this evening (Eastern time), and become a typhoon Tuesday night or Wednesday morning. It is possible that this new system could come close to the northern Philippines late in the week or next weekend as a typhoon. Elsewhere, former Tropical Storm Lupit is now extratropical. Its remnants continue to bring rain and wind to Japan as it moves parallel to Japan's Coast.
ATLANTIC/EASTERN PACIFIC
Closer to the U. S., the Atlantic and eastern Pacific basins remain quiet. Typically by this time of year, 93% of the Atlantic hurricane season is over and about 98% of the eastern Pacific season is done. So, while a late-season storm cannot be ruled out in either basin, historically, chances are slim.

Why is it that people who never pay attention to the weather are always the first to complain.
