Those who suffer with allergies and asthma, all know that certain times of the year can wreak havoc on their bodies. I myself suffer from allergic asthma, and late spring is one season that wreaks havoc on my body. While some may feel the change in air quality in advance, it may sneak up on others. I want to incorporate allergy and asthma forecasts into the mix, as a way to alert all sufferers in advance. Tuesday’s allergy forecast remains beneficial, for those with allergies. Lately, this seems to be a rare occurrence for  much of Pennsylvania, and other parts of the country. While tree pollen counts will remain on the

A wet Tuesday is in store for much of the state. the next round of rain and thunderstorms will accompany a low-pressure system pushing through the East into midweek. A broad swath from New England to the Southeast could pick up 1 to 2 inches of rainfall through Tuesday as the low and its trailing cold front slide across the region. If you are sick of rain by now, next weekend will be drier and warmer for much of the Northeast. Next weekend, the jet stream will bulge northward into southeastern Canada, allowing high pressure to develop at the surface over the eastern U.S. This means there will be an increased chance for near-

A marginal risk has been decreased for much of the state on Monday. The upper trough situated over the upper Great Lakes/Midwest will develop south/southeast on Monday. This will bring a belt of enhanced westerly flow across the OH Valley to the mid-Atlantic region. As this occurs, a cold front will drop southward across OH, western PA and western NY through the evening. Severity of these storms may be isolated or non-existent. This is a change from the previous forecast that we shared recently. Damaging winds and severe storms are not likely at this time. Any changes that are made with the forecast, will be updated as they are issued by

The marginal and slight risk areas have been trimmed further on the east side to remove all of western NY and much of PA. Ongoing rain and cloud cover has prevented stronger heating and destabilization of the boundary layer and hence, any appreciable severe threat. Bands of showers and isolated thunderstorms are still possible throughout the evening. The risk of damaging storms is relatively low. Forecasts will be updated as they are submitted by the NWS.

The Storm Prediction Center has upgraded the marginal risk for today, to a slight risk. This upgrade means that damaging storms are likely. Areas that were placed in a general thunderstorm risk, have now been upgraded to a marginal risk. A small portion of the state remains in a general risk as of right now. In concert with these developments, the surface frontal system accompanying broader mid-level troughing over the Great Lakes area will continue to fracture, with diffuse frontal bands becoming focused west-east across the Great Lakes and Ohio Valley region. Relevant for severe convective concerns, a corridor of relatively rich moisture will extend eastward from the middle Mississippi Valley

Storms to linger through Monday, June 5, 2017. Forecast models show organized rotating updrafts but storm type may be mixed mode with clusters/line segments along with a few supercells. This will introduce 5% severe probability for convection along the front, but 15% severe may be needed in later outlooks if adequate buoyancy is present. Hail and wind are the primary risks with this activity. Storms will make their way into the state Sunday evening, and will stick around for the majority of Monday. Sunday’s forecast remains without change, as Monday’s outlook places the majority of the state in a marginal risk. As always, stay weather ready in case of any severe weather.

A slight risk has been issued for portions of Erie and surrounding areas on June 4, 2017. This system should reach the lower great lakes by evening. Damaging winds and hail are the primary threats with convection that evolves along the cold front. A marginal risk has been issued for a small portion of the state, while the rest has been placed in a general thunderstorm risk. As with a slight risk, severe storms are likely in the marginal areas, but may not be as severe as those areas that have been placed in the slight risk areas. Stay weather ready and up to date in case any warnings or watches

Scientists using data from NASA’s Lunar Reconnaissance Orbiter, or LRO, have identified bright areas in craters near the moon’s south pole that are cold enough to have frost present on the surface. The icy deposits appear to be patchy and thin, and it’s possible that they are mixed in with the surface layer of soil, dust and small rocks called the regolith. The researchers say they are not seeing expanses of ice similar to a frozen pond or skating rink. Instead, they are seeing signs of surface frost. The frost was found in cold traps close to the moon’s south pole. Cold traps are permanently dark areas — located either on the floor

Motivated by adventure, science, and awe at the power of nature, stormchasers are risking it all to get closer to tornadoes than ever before. The tornado that touched down in an open field at 6:03 P.M. on Friday, May 31 took the name of the town El Reno, but it was not a single tornado in the traditional sense, nor was it confined to one municipality. Part of a larger system that dropped eight tornadoes across Oklahoma’s midsection, it traveled 16.2 miles, enveloping lines of cars caught at a standstill in rush-hour traffic on Interstate 40 before dissipating at 6:43. Panicked motorists began crossing the median and driving up embankments, unsure

Locally strong thunderstorms will once again take aim at the northeastern United States later today. The same storm responsible for Tuesday’s thunderstorms will bring a renewed threat of locally violent thunderstorms this afternoon and early evening. While the above areas are at greatest risk, it is not out of the question for an isolated strong thunderstorm to rattle other parts of the Northeast and mid-Atlantic into the evening. More of the thunderstorms will disrupt outdoor plans and create slower travel. Remember that as soon as thunder is heard, the risk of being struck by lightning is present. The risk of strong thunderstorms will finally wane on Thursday as drier and less
