Odds of a Weekend Tropical Depression Rise; Dodge City Dodges Multiple Tornadoes


Showers and thunderstorms continue over portions of the Bahamas and nearby waters in association with an upper-level trough interacting with a weakening cold front. On Wednesday morning, NHC designated this area of interest as Invest 91L. This activity is expected to coalesce into an area of low pressure on Friday a few hundred miles north of the Bahama Islands. This low has the potential to develop into a tropical depression as it moves northwest towards the Southe...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3309">Read More</a>

A Memorial Day Weekend Tropical System For the Southeast U.S.?


We're fast approaching the official June 1 start of the Atlantic hurricane season, and we already have an area of concern to watch for possible genesis of a tropical depression during the coming Memorial Day weekend. An area of low pressure is expected to form on Friday near to or a few hundred miles north of the Bahama Islands, and this low has the potential for tropical development as it moves northwest towards the Southeast U.S. coast. Sea Surface Temperatures (S...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3308">Read More</a>

A Week of Storminess on the Southern Plains Dryline


With climatology in the driver’s seat, a busy week of potentially tornadic weather will take shape from Nebraska to Texas. This prototypical late-May pattern is being driven by a very slow-moving upper low centered near Montana and an upper trough extending to California. Moderately strong southwest flow ahead of this trough will persist nearly all week across the Southern Plains--a recipe for tornadic trouble this time of year, given the presence of very warm, mo...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3307">Read More</a>

Arctic Sea Ice Goes Far Beyond Record Low Extent for May


The sea ice that coats the Arctic Ocean each winter and erodes each summer is going through its most depleted spring since modern observing began. The Danish Meteorological Institute reported the lowest sea ice extent of any April in the Arctic’s 38-year-long satellite record. As luck would have it, the primary satellite sensor used by the National Snow and Ice Data Center (NSIDC) for extent measurement began producing spurious data in April. A similar microwave i...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3306">Read More</a>

April 2016: Earth's 12th Consecutive Warmest Month on Record


Keeping a year-long string of record-warm months going, April 2016 was by far the planet's warmest April since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Wednesday. In the NOAA database, April 2016 came in a full 1.10°C (1.98°F) warmer than the 20th-century average for April of 13.7°C (56.7°F), as well as 0.28°C (0.50°F) above the previous record for April, set in 2010. This is a huge margin for breaking ...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3305">Read More</a>

Deadly Rains From Tropical Cyclone One Kill 34 in Sri Lanka, Leave 134 Missing


One of the deadliest weather-related disaster of 2016 is unfolding in Sri Lanka, where heavy rains from Tropical Cyclone One have triggered flash floods and landslides that have killed at least 34 people and left 134 missing. The rains began on Monday, when an area of low pressure that formed on the leading edge of the advancing monsoon began to consolidate just to the southeast of Sri Lanka. Hours of torrential rains triggered massive mudslides Tuesday evening that...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3304">Read More</a>

An Oklahoma Tornado Rewrites the Rule Book


Overshadowed by the mighty EF4 and EF3 tornadoes that tore across south-central Oklahoma last Monday, May 9, another less damaging twister--from the same thunderstorm--has left seasoned scientists both astonished and fascinated. This tornado, which struck near Roff, OK, was rated an unexceptional EF1 on the Enhanced Fujita Tornado Damage Scale. However, the Roff tornado stands out in several other ways.

—It was an anticyclonic tornado, meaning that it r...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3303">Read More</a>

A Quiet Start to the Eastern Pacific Hurricane and Northwest Pacific Typhoon Seasons


The 2016 Eastern Pacific hurricane season officially begins on Sunday, May 15, and should be quieter than the crazy 2015 season. Last year set a record for the most major hurricanes (Category 3 or higher) ever recorded in the Eastern Pacific east of 140°W, with nine such storms (reliable records go back to 1971.) One of those 2015 hurricanes was Earth's strongest tropical cyclone ever measured, Hurricane Patricia of October 2015, which reached astonishing sustained...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3302">Read More</a>
