Western Drought Intensifies, Leads to Deadly Wildfires
By Daniel Yawitz
Follow @dyawitz
A record-breaking heat wave intensified drought conditions in much of the West during the past week, with 72 percent of the land area in the 10 Western states now in drought conditions, according to the latest update to the U.S. Drought Monitor.

The worst impacts of the drought are concentrated in the Southwest: New Mexico, Texas, Southern Colorado and the western parts of Kansas, Oklahoma and Nebraska all contain land that is under extreme or exceptional drought. The hot weather — Denver had its earliest 100-degree day on June 12 — served to exacerbate existing drought conditions and helped fuel deadly wildfires in Arizona, California, Colorado, Nevada, New Mexico, and Oregon. In California, 2013 has been the driest year on record to date, and the lack of rainfall is making the state more vulnerable to wildfires.
“The overall pattern of hot and dry conditions, combined with year-to-date below normal precipitation, led to continued deterioration of pasture and rangeland conditions across Arizona, California, Nevada and New Mexico,” said David Simeral of the Western Regional Climate Center, in a statement accompanying the Drought Monitor.
According to the U.S Department of Agriculture (USDA), 100 percent of the range and pasture land in New Mexico is in poor or very poor condition.
The ongoing problem of drought was a major focus of the spring State of the Climate report, which was released by the National Oceanic and Atmospheric Administration this week. This year, the period from March to May has been the second-driest on record in New Mexico, where water supply concerns are escalating.
By contrast, Iowa, Illinois and Wisconsin are all having their wettest year to date. Heavy rainfall in the Midwest and the Mississippi River Valley caused the Mississippi River at St. Louis to crest at its sixth-highest level. As of this week, 44.13 percent of the continental U.S. is under moderate drought or worse, and all of that land is now in states west of the Mississippi River.

Across the rest of the country, drought conditions have improved significantly from the nearly coast-to-coast drought that was present last summer. On the East Coast, Tropical Storm Andrea washed away all lingering traces of drought, including those in Florida, which had been nearly engulfed by moderate and severe drought as recently as February.
In the Midwest, the unusually wet March-May period has pushed the boundary of the drought to the west, allowing states like Iowa, Minnesota, Wisconsin, and the eastern parts of the Dakotas, Kansas and parts of Oklahoma to emerge from the drought. The sudden shift in precipitation has made flooding, rather than drought, a bigger concern in states on the Upper Mississippi River.
On Oklahoma rainfall maps, the state appears to have been cleaved in half, with the south central and eastern areas receiving above-average precipitation during the past month, and western parts of the state left high and dry. According to the Oklahoma State Mesonet, which operates a network of weather stations across the state, the town of Hooker in the Oklahoma Panhandle, received just 0.08 inches of rainfall during the month of May. That was the second-lowest May total for the town since record-keeping began in 1906. Yet in Oklahoma City, about 250 miles away, had its wettest May on record, with 14.52 inches of rain. It was Oklahoma City's second-wettest month of any month, behind the 14.66 inches it received in June, 1989.

[h=2]Heat Wave for Eastern Europe
[h=6]By Eric Leister, Meteorologist [h=5]June 14, 2013; 11:24 AM
Share |
A change to unseasonable warmth is expected to begin this weekend and continue through much of next week for eastern Europe.
A strong upper-level low pressure dropping southward into Spain will force a ridge of high pressure to build over eastern Europe.
The upper-level low will sit and spin over Spain and France for much of the week allowing the ridge to strengthen and produce a heat wave for parts of southeast Europe.
The core of the heat will build from Hungary and Serbia into Romania and Bulgaria leading to a heat wave. Temperatures will in these areas will be 10-20 degrees above normal.
Some major cities that will be impacted by this heat wave include Budapest, Sofia, Belgrade and Bucharest.
The only escape from this heat will be spotty afternoon thunderstorms that develop over the higher terrain of the region. A few of these storms will drift into the lower elevations, but most areas will just remain dry and hot.
On the flip side, a cool and wet week is expected across western Europe as the upper-level low brings several days of rain from Spain into France.
During the second half of the week, the stormy weather will shift into areas from eastern France to the Germany and the Baltic states.
Depending on the exact track of the storm, locally heavy rainfall could fall over areas recently impacted by record flooding in central Europe. Anyone in this region should closely monitor the situation, as renewed flooding could occur.

با همه ي احترامي كه براي آقاي اصغري قائل هستم ولي اميدوارم پيش بيني سايتهاي هواشناسي براي ما درست دربياد :نیش:
من شايد كسي نباشم كه توي زمستونا روياي دماهاي تا بي نهايت زير صفر رو داشته باشم، يا توي پاييز و بهار آرزوي دماي زير نرمال رو ، ولي از تابستاني كه روزاش زياد جهنمي نشه و شباي خنكي داشته باشه استقبال مي كنم. چون چنين تابستوني واقعا حال و هواي خاصي براي من خواهد داشت. :141: :بغل:
(البته من منظورم از تابستان خرداد، تير، و مرداد هستش) :18:
اين صحبتشون تقريبا خلاف چيزي بود كه قبلا عرض كرده بودن. احتمالا حاصل بررسي هاي جديدشون هست. :گل:
ولي خب اين ميتونه تمام محاسبات و معادلات رو به هم بزنه (بخصوص براي ما)، كه البته شايد اين تغيير چندان هم بد نباشه! :93:
