An Exceptionally Slow-Starting Typhoon Season; 95L Fizzles

http://www.wunderground.com/blog/JeffMasters/an-exceptionally-slowstarting-typhoon-season-95l-fizzles

Residents of the Northwest Pacific have enjoyed an unusually late start to the typhoon season this year, despite the fact that ocean temperatures have been running about 1°C (1.8°F) above average. Though there has already been one tropical depression, the basin has yet to see a named storm. Typically, 90% of all Northwest Pacific seasons see their first named storm by May 1 (thanks to Mike Fiorino for this stat.) Four named storms, two typhoons, and one intense ty...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3341">Read More</a>

http://www.wunderground.com/blog/JeffMasters/tornado-and-derecho-threat-from-midwest-to-appalachians

A near-classic early-summer sequence of potentially tornadic storms followed by destructive straight-line winds is in the cards for the Midwest on Wednesday afternoon and evening, with the wind-packing storms possibly approaching the mid-Atlantic states on Thursday morning. In its Day 1 outlook updated at 12:30 PM EDT Wednesday, NOAA’s Storm Prediction Center is calling for a moderate risk of severe weather (the second highest of SPC’s five risk categories) from...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3339">Read More</a>

Fierce thunderstorms capable of spawning significant tornadoes and very high winds are possible Wednesday afternoon and evening across an east-west corridor that will lie near or across the Chicago area. NOAA’s Storm Prediction Center is predicting a moderate risk of severe weather for Wednesday PM extending from southeast Wisconsin and northeast Illinois to southeast Michigan and northwest Ohio (see Figure 1). “Moderate” is actually the second-highest categor...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3338">Read More</a>

http://www.wunderground.com/blog/JeffMasters/danielle-the-atlantics-earliest-4th-storm-on-record-115120-heat

Tropical Storm Danielle formed on Monday morning in the Gulf of Mexico's Bay of Campeche, but won't be around long. The storm's west to west-northwest motion will carry the storm inland over Mexico between Veracruz and Tampico by Monday evening. With top winds of just 45 mph as estimated by the National Hurricane Center in their 11 am EDT Monday advisory, heavy rain is expected to be the primary threat from the storm. Satellite loops show a large area of intense thu...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3337">Read More</a>

Gulf of Mexico's 94L Close to Tropical Depression Status

http://www.wunderground.com/blog/JeffMasters/gulf-of-mexicos-94l-close-to-tropical-depression-status

A tropical disturbance over the southern Gulf of Mexico (Invest 94L) has grown more organized since Saturday, and appears likely to develop into a tropical depression on Sunday or Monday as the storm heads west-northwest at 10 mph. Satellite loops late Sunday morning showed the disturbance had acquired a well-developed surface circulation, but 94L's heavy thunderstorms were not well organized and were relatively sparse, as seen on Mexican radar out of Sabancuy.

A tropical disturbance over Mexico's Yucatan Peninsula (Invest 94L) has the potential to develop into a tropical depression on Sunday or Monday over the Gulf of Mexico's Bay of Campeche as the storm heads west-northwest at 10 mph. Satellite loops late Saturday morning showed the disturbance had developed a moderate degree of spin, with a few low-level spiral bands already apparent over the Bay of Campeche; Mexican radar out of Sabancuy showed a few heavy rain shower...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3335">Read More</a>

NOAA and NASA: Earth’s Warmest May on Record

http://www.wunderground.com/blog/JeffMasters/noaa-and-nasa-earths-warmest-may-on-record

The warming influence of the intense 2015 - 2016 El Niño event is waning, but May 2016 was still the planet's warmest May since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Thursday. In the NOAA database, May 2016 came in 0.87°C (1.57°F) warmer than the 20th-century average for May, beating the previous record for May, set in 2015, by 0.02°C.

U.S. Heat Builds: Parts of Southwest May Approach All-Time June Highs

http://www.wunderground.com/blog/JeffMasters/us-heat-builds-parts-of-southwest-may-approach-alltime-june-highs

Earth’s warmest year on record so far will make its presence felt in North America during the latter half of June. A massive dome of high pressure at upper levels will take shape across the United States this weekend and persist through next week. Subsidence beneath the high pressure will warm the atmosphere and help temperatures to soar well above average over large parts of the nation. The most immediate concern is across the Southern Plains and Mississippi Vall...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3332">Read More</a>
