HEAT INDEX: Did you know it can feel hotter than the air temperature - because of humidity? This index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature. To find the Heat Index temperature, look at the NWS Heat Index Chart or see the Heat Index Calculator at weather.gov/safety/heat-index

PALMER HYDROLOGICAL DROUGHT INDEX (PHDI): Index Background, PHDI and Drought.gov Maps; and Current/Projected Condition Maps. Part of the suite of indices developed by Palmer in the 1960s with the United States Weather Bureau. Based on the original PDSI and modified to take into account longer-term dryness that will affect water storage, streamflow and groundwater. PHDI has the ability to calculate when a drought will end based on precipitation needed by using a ratio of moisture received to moisture required to end a drought. There are four drought categories: near normal, which occurs approximately 28%–50% percent of the time; mild to moderate, which occurs approximately 11%–27% percent of the time; severe, which occurs approximately 5%–10% percent of the time; and extreme, which will occur approximately 4% of the time.
US DROUGHT MONITOR: Produced through a partnership between the National Drought Mitigation Center at the University of Nebraska-Lincoln, the United States Department of Agriculture, and the National Oceanic and Atmospheric Administration. 402-472–6707; Note, this monitor monitor focuses on broad-scale conditions.

AIR QUALITY: Air Quality Index (AQI), via Google Maps with its new Air Quality layer. Simply click the “Layers” menu icon (same button you would use to change mode to satellite or street view). It now provides an option to include AQI numbers on your map. Click on an AQI and it will show the sources and timing for that data. The format of the AQI is a number from 0 to 500, with the quality decreasing as the number goes up. The AQI includes smoke contributions as reported by the NOAA.

See forecasts from WMO Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS) at sds-was.cimh.edu.bb/
LARGE SEASONAL DUST PLUMES: Significant dust plume occur annually and seasonally, arriving here in our Spring through Summer seasons. The plumes complete the 5,000 mile journey from Africa to Texas, carrying some 180 million tons of Saharan desert dust across the Atlantic each year. These plumes play an important role in nature. This dust helps fertilize by transporting minerals such as iron and phosphorus. The particles making these plumes of dust are very small, about 1-2.5 micrometers. These hot, dry particles are respiratory irritants, so air quality is reduced when you are surrounded by thick plumes. A plume will often have enough dust in it to drop our air quality to the "moderate" range, meaning that while it likely is hazy outside, the average person won't even notice an impact on their breathing. However, those with very sensitive or compromised respiratory function might experience complications and may want to reduce their time outdoors.
AIR POLLUTION WORLD-WIDE VIDEO: View. Stunning NASA video of GEOS5 aerosols (in color, on YouTube), indicating that "air pollution from Asia strengthens extratropical cyclones, a type of storm system that drives much of our country's weather". Video shows pollution streams over a multi-year period indicated by the dates displayed.
