Irma remains a significant Category 4 hurricane late this afternoon with sustained winds around 155 mph. The sheer size of Irma is quite menacing, and spatially the hurricane covers an area roughly the size of Texas. Given this, sustained tropical storm force winds (in excess of 39 mph) will encompass the majority of the Florida peninsula over the coming days. The sustained hurricane force winds (in excess of 74 mph) will extend outward as much as 80 miles from the center! Note that hurricane force gusts could occur at locations over 120 miles from the center.Topics: WeatherOps | Tropical | Hurricane |
Cold weather is expected for the Oklahoma City Memorial Marathon on Sunday, April 30. There can be a variety of weather conditions in late April when this marathon is run. Past races have been warm and muggy, with relatively light breezes. Other races have been in jeopardy due to thunderstorms. The start of the 2014 marathon was delayed by nearly two hours as thunderstorms moved into the area prior to the start.Topics: WeatherOps | Live Events |

The severe weather threat will continue across the Plains and into the Mid-Mississippi Valley this weekend and into next week. Areas from the central Gulf coast and northward into the Lower and Mid-Mississippi Valley will likely see severe thunderstorms with damaging winds, large hail, and a few tornadoes on Saturday as a cold front pushes through the region. Ahead of this front, plentiful moisture will be drawn northward from the Gulf Mexico, providing the fuel for this thunderstorm activity. While storms are expected to be mostly linear in nature, a few discrete supercells may form during the afternoon hours and these will have the capability to produce a few tornadoes. Into the evening on Saturday the main threat will be strong and damaging winds.Topics: WeatherOps | Thunderstorm |
Bone chilling cold is in store for several NFL games on Sunday. A much advertised Arctic air intrusion will grip most of the central part of the United States by Saturday and into Sunday. While bitterly cold temperatures for NFL games are typically expected in January during playoff time, many locations in the Upper Midwest and Plains will experience them this weekend. The ambient temperature when the Chicago Bears host the Green Bay Packers at Soldier Field on Sunday at 12:00 PM CST is expected to be right around or just under 0°F. Add in a brisk northwest wind around 15-20 mph, and wind chills below -20°F will be possible!Topics: WeatherOps | Frontier |
During the late fall, winter, and early spring one of the primary weather concerns for the Gulf of Mexico is the passage of strong cold fronts. Abrupt wind shifts, sustained winds in excess of 25 knots, gusts in excess of 30 knots, and seas in excess of 8 feet are typically associated with these fronts.Topics: WeatherOps | Offshore | Oil & Gas | Tropical |
The Mediterranean Sea is not a region of the world that you typically think of as being a tropical cyclone hotbed. Over this past weekend a cyclone with both tropical and non-tropical characteristics formed in the Ionian Sea between Italy and Greece. The development of these systems, known as medicanes, is quite rare. When they do form, they often have characteristics of both a fully tropical cyclone and a non-tropical cyclone.
Despite a rapid greening of vegetation during the past few weeks across areas generally along and east of the I-35 and I-44 corridors, there are still several areas across the region with dry/dormant vegetation. As has been the theme many times this spring, gusty winds, very low relative humidity, and high temperatures will lead to extreme to critical fire danger today and Wednesday.Topics: Wildfire |
