First time here 😍 If you’re around this week for #AMSMadisonSummit, I’ll be presenting two projects from my PhD! Monday, 11 am: “A Cyclone-Centered Examination of Low-Level Jet–Terrain Interactions on Observed Precipitation Patterns in Northeastern United States Winter Storms”

Today I had the opportunity to visit the @nyswrcc.bsky.social at UAlbany! Alongside @latinwx.bsky.social and as part of my PhD research @climasillinois.bsky.social we are collaborating with NYSWRCC to better understand how emergency practitioners interpret and use winter weather forecasts

Captured some incredible lightning in Champaign this morning before a tornado warning was issued.⛈️ Slowed this video down as much as I could. Appears the tower in the distance was also struck initially if you squint. @ztresearch.bsky.social #ilwx

Thundersnow in Downtown #Chicago captured by the Chicago Loop Live webcam! This was the first one around 12:23 am. There were two lightning flashes afterwards each spaced roughly 10 mins apart #ilwx ❄️⚡️

First evidence of thundersnow this evening is on the western periphery of the mesolow, likely over the steel plant near Indiana Dunes National Park. No shortage of tall objects there…more ⚡️ possible as the night goes on near #Chicago

Strong wording regarding lake-effect snow from NWS Chicago this evening. First snow of the season looking to be quite impactful for the #Chicago metro. Monday morning’s commute could be treacherous ❄️ #ilwx

(1/4) Lots of talk about the potential for anomalously cold temps and lake-effect precip (snow?) next week. Details remain uncertain at this lead time, however EOF analysis can provide some insight. Right now, the largest upper-level pattern differences in the models lie in the trough amplitude...

This may be one of the first true tests of the Euro AIFS with a warm-core Nor’easter. Interestingly, the latest 12z run of the deterministic Euro is very different than the AI version. With such a complex meteorology setup it will be interesting to see how this pans out.

Read the latest key messages regarding the development of a strong coastal low this weekend. Significant coastal impacts are expected along much of the U.S. East Coast through early next week. Find your local forecast office to keep up with the latest at weather.gov.

Graphic relaying the Key Messages for a forecast strong coastal low expected along the east coast this weekend.
- A coastal low is expected to develop off the coast of the Southeast US early Saturday and strengthen through the weekend, bringing significant coastal impacts to parts of the US East Coast through early next week.
- The combination of persistent, strong onshore winds, high surf, and high astronomical tides may lead to major coastal flooding for some Mid-Atlantic communities. Coastal residents are urged to heed warnings for their local National Weather Service office and always follow guidance from local officials.
- High surf is expected on many East Coast beaches, which will generate strong rip currents and likely lead to areas of beach erosion.
- There is an increasing threat of wind gusts in excess of 55mph and periods of heavy rain for coastal areas of the Mid-Atlantic. This may lead to scattered power outages and isolated to scattered instances of flash flooding.

Finally some persistent rain last night in Champaign-Urbana but how much rain fell really depended on what side of town you’re on. Almost an inch less of rain in Champaign compared to Urbana. Some of those localized downpours didn’t quite make it west. #ilwx #cocorahs

Incredible +CG flash!! Negative leaders propagate right to left incloud, then a positive leader develops downward from the decaying negative leader causing a +CG return stroke. Positive leaders with recoil leaders visible below cloud base following the return stroke.

M.S. in Atmospheric Sciences 🎓✅🥳 Pursuing a graduate degree was a dream of mine, but one I didn’t always believe was possible! I’m thankful for my teachers along the way that instilled belief in me. So excited to remain @climasuiuc.bsky.social as a research assistant for my PhD!
