Areas of Extreme Heat and Excessive Rainfall Potential

Dangerous and extreme heat will remain across portions of the central U.S. this week, persisting across the mid to lower Mississippi Valley, Gulf Coast, southern Plains and portions of Texas. A heat wave over the Southwest U.S. will peak this weekend. Heavy to excessive rainfall may produce flash flooding from the Delmarva Peninsula north into the Hudson Valley today and tonight.

The National Weather Service Cooperative Observer Program (COOP) is a network of over 11,000 volunteer observers across the nation. The NWS in Santa Teresa currently maintains around 30 COOP sites (see fig. 1). The National Weather Service (NWS) will design and set up the site and install the equipment. The NWS also trains the observer to utilize the equipment in taking the observations and to do simple maintenance; otherwise the NWS provides the significant repair and maintenance. These observations are helpful, both for short term forecasts and maintaining a climate base to help track long term trends in the climate.

The great majority of observers take their observations at or near their residence, although a few businesses or government agencies also take observations. These observers take one observation each day of the year, usually either at 0800 or 1800 local time. The observation can be as simple as recorded rainfall, or more often reported, max/min temperatures, rainfall, snowfall and snow depth. A few sites with agricultural interests even report evaporation and soil temperature. In the past, observers filled out a paper form and sent the form end at the end of each month. Today, many observers transmit their observations electronically via telephone or computer.
