Day 4-Round 2 Of The Summer Heatwave
The first heat wave lasted from the 27th of June through the 7th of July before temperatures backed of to average on the 8th of July. The last time we had an average temperature for the day below average was back on 6/22. the last time temperatures were 10 degrees below average or more was back on June 1st. So including today this will be the 25th straight day with temperatures above average for KC and there is no end in sight.
We’ve had 9 days with highs of 100° or higher, we’ll be awfully close today and we should make it if not do better for the next several days with highs in the 100-105° for the region. The hottest stretch may actually be Sunday through Tuesday or Monday through Wednesday of next week if some of the modelling is correct with highs eclipsing 105°. That remains to be seen but the pattern certainly would support this as the drought worsens and the terrain shows more and more signs of stress and dormancy.
Is there any hope that things could change. For the time being not really. There may be a weak wind shift that could create clouds and isolated storms on the MO side towards the NE of the metro on Friday. There may be some sort of week front next week to knock us down into the 90s sometime later in the week. It does look like however that we are in it and it will continue to get a lot worse before it gets any better. it should be noted that IF we get any relief next week, whatever relief there is will be VERY temporary (if relief is the right word) and we’ll quickly scorch again heading towards the end of the month.
How bad is it? The drought is even showing up on some of the special satellites that are looking at the terrain of the Midwest.
Here is some of the discussion about the image from the site http://earthobservatory.nasa.gov
Farmers across the United States hoped for rain in July 2012 as a drought of historic proportions parched key commodity crops, including corn, soybeans, and wheat. On July 11, the United States Department of Agriculture announced that more than 1,000 counties in 26 states qualified as natural disaster areas—the largest total area ever declared a disaster zone by the agency.
The extent of the damage to crops is depicted in this vegetation anomaly map based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The map contrasts plant health in the central United States between June 25 and July 10, 2012, against the average conditions between 2002 and 2012. Brown areas show where plant growth was less vigorous than normal; cream colors depict normal levels of growth; and green indicates abnormally lush vegetation. Data was not available in the gray areas due to snow or cloud cover. The image is based on the Normalized Difference Vegetation Index (NDVI), a measure of how much plant leaves absorb visible light and reflect infrared light. Drought-stressed vegetation reflects more visible light and less infrared than healthy vegetation.
The most severe damage to crops appears to be centered on Missouri, Arkansas, Oklahoma, Texas, Kansas, Nebraska, and South Dakota. Crops in much of the upper Midwest—southern Wisconsin, Michigan, Indiana, southern Illinois, western Kentucky, and western Tennessee—also show signs of strain. States in the Mountain West that are in the midst of a busy wildfire season—Montana, Wyoming, and Colorado—have also experienced marked declines in the health of vegetation. The drought has been less severe in Iowa, a key corn-growing state.
We’ve had 9 days with highs of 100°+. St Louis is up to 10, Denver 9, Indianapolis 6, Washington DC has had 5 and Chicago has had 4.
And so it goes, and it’s not good!
