Meteorology Monday (6-9-25): The Cap
Have you ever heard a meteorologist use the term 'cap' or 'break the cap'? On this week's edition of Meteorology Monday, 18 Storm Team Meteorologist Alivia Colon explains a key step to thunderstorms development- breaking the cap. We know that air usually gets colder with height, and we know that heat rises. When the sun heats up the surface during the day, updrafts of warm air rise and the cooler, surrounding air sinks. As long as the surrounding air remains cooler with height, updrafts continue to rise. This process feeds into the water cycle and is how clouds form in the sky. Sometimes, there is a layer of air in the atmosphere that is warm, and we call this layer an inversion, or a capping inversion. This is because when the updraft reaches this layer, it is no longer warmer than the surrounding air, and the warmer layer limits, or caps, clouds from growing much taller into the towering cumulus clouds that form thunderstorms. If the updraft is warm enough, or more moisture is filtered in, or even if the cap is thin or weak in some areas, the updrafts can 'break the cap' and rapidly develop into a strong or severe thunderstorm. Once the thunderstorm happens, your 18 Storm Team and local NWS offices will be all over keeping you safe and informed, so you're next steps will be to seek shelter and stay weather aware.

Meteorology Monday (6-2-25): 2025 Atlantic Hurricane Season Outlook
Elmira, N.Y. (WETM)- Happy Meteorology Monday! It's June, which means that the hurricane season has officially begun in the Atlantic basin. On this week's edition of Meteorology Monday, 18 Storm Team Meteorologist Alivia Colon breaks down the National Oceanic and Atmospheric Administration's (NOAA) first hurricane season outlook and how it compares to last year's. To start, this year, there is a 60 percent chance for above normal activity, with a 30% chance for near normal activity, and the remaining 10 percent is for a below normal season. These numbers may not be high, but they do indicate that a slightly more active than normal season is possible and will need to be closely monitored before we head into peak season. Last year, NOAA forecasted a 90% chance for above normal activity by the time we got our second outlook, and that's exactly what happened: 18 named storms, 11 of which were hurricanes, and 5 were major. The forecast not only played out accurately, but we managed to do so even with an unusually quiet mid-season when activity typically peaks. If you remember, we had major storms very early in the season, and well into the late season as well. This year, our numbers only lean above average, but the chance for more activity is certainly present. This is based on factors such as warmer ocean temperatures, a forecasted ENSO neutral year, or a year without El Nino or La Nina, weaker forecasted wind changes with height, and a more active West African Monsoon forecasted, which is known to be a primary starting point for Atlantic hurricanes NOAA releases an outlook at the start of the season, and a second outlook before peak season, so make sure to keep an eye out for updates as the season ramps up. For more information, you can read about the full outlook and how NOAA is preparing for the season on their website here. Copyright 2025 Nexstar Media, Inc. All rights reserved.

Meteorology Monday (5-19-25): Frost
Elmira, N.Y. (WETM)- Happy Meteorology Monday! Spring in the Twin Tiers usually brings warmer air, but it isn't rare for a few chilly nights. On this week's edition of Meteorology Monday, 18 Storm Team Meteorologist Alivia Colon talks about one concern that can come with these cooler nights: frost. We often talk about how on clear nights, the heat that we got from the sun's radiation during the day can easily escape back to space when there are no clouds to keep it at the surface. This is known as radiational cooling, and is the key factor necessary for frost. When air temperatures get into the upper 30s and winds are calm, the cooler, denser air sinks, creating a cooler, near freezing layer near the ground. When we have moisture in the air, the water molecules freeze onto the freezing surface, creating ice crystals, or frost. An area-wide frost advisory is in place for the Twin Tiers because we are tracking the chance for each of these conditions to set up overnight. Take steps to prepare and protect your sensitive plants. Copyright 2025 Nexstar Media, Inc. All rights reserved. This material may not be published, broadcast, rewritten, or redistributed.

Meteorology Monday (4-28-25): Hail
Elmira, N.Y. (WETM)- Happy Meteorology Monday! Spring in the Twin Tiers usually brings a transition from wintry weather to more frequent severe weather patterns. On this week's edition of Meteorology Monday, 18 Storm Team Meteorologist Alivia Colon talks about a form of frozen precipitation that should not be mistaken for your usual wintry weather: hail. Meteorology Monday: Thunderstorm safety When we talk about frozen precipitation in the winter, we are usually talking about snow, sleet, and freezing rain, which depend on the temperature in different layers of the atmosphere. However, when we talk about hail, we are talking about supercooled water droplets within a thunderstorm that get carried up and down through thunderstorm updrafts. As they lift and fall between the freezing layer within a storm, layers of ice form around the the hailstone weighs more than the force of the updraft, the stone falls as hail. Depending on the strength of these updrafts, you can get hailstones as big as softballs and CDs. Severe weather season is here: learn how to protect yourself Tomorrow, a cold front will bring showers and storms, bringing a moderate chance for hail and a moderate to high chance for severe winds. Be ready to be weather aware. Meteorologist Alivia Colón: Facebook I X I Instagram Copyright 2025 Nexstar Media, Inc. All rights reserved.

Meteorology Monday (4-14-25): Thunderstorm safety
Elmira, N.Y. (WETM)- This week is Severe Weather Awareness Week in Pennsylvania. A severe thunderstorm is a storm that produces 58 mph winds or higher, tornadoes, or hail 1 inch or larger. On this week's edition of Meteorology Monday, 18 Storm Team Meteorologist Alivia Colon discusses how you can stay safe during a severe thunderstorm. During a thunderstorm, seek shelter indoors, away from windows, and avoid electronics and unplug. Tune into your local TV/Radio/NOAA Weather Radio stations for updated information. Take it seriously- lightning is a killer. Severe weather season is here: learn how to protect yourself If you are caught outside, stay away from tall objects like trees and poles, metal objects like fences, and pools or bodies of water. If you are in a car, you should be safe if it has a metal roof, but convertibles and motorcycles are not safe. Seek low-lying ground if you absolutely can't find shelter. Thunder is the sound of lightning striking the ground, therefore, once you hear it, you're within striking distance. After seeking shelter, you should stay inside until 30 minutes after the last rumble of thunder. If you're interested in becoming a trained weather spotter for the NWS this severe weather season, you can find information on when classes will be available to the Twin Tiers on the NWS Binghamton and State College websites.
