Northern Maryland Weather Forecasting

Northern Maryland Weather Forecasting This is a local weather service for the Carroll, Baltimore, Harford, and Cecil county areas. I grew up in Harford County, MD, specifically in Forest Hill.

For those of you who don't know me, my name is Maximilian (Max) Magness. I am currently an Atmospheric Scientist for CPP Wind Engineering and Air Quality Consultants out of Windsor, CO. Most of my work surrounds the statistics of wind affects on buildings and other structures. My love for weather and climate began as a young child, mainly due to me being afraid of thunderstorms. I graduated from N

orth Harford High School in 2015 and was part of the Agriculture Magnet Program. I went to Harford Community College for a year before transferring to Salisbury University. During my time at Salisbury University, I conducted multiple research projects on anything from tornadoes, to hail, to climate change, etc. I graduated with B.S. in Geography with tracks in both Atmospheric Science and GIS from Salisbury University in May 2019. I decided to apply to graduate schools my senior year and choose to go to Mississippi State University after much thought. While I was attending MSU, I was a teaching assistant for multiple classes, Meteorology Intern at MemphisWeather.net, and Graduate Assistant for the Mississippi State Climate Office. My thesis is on Synoptic-scale characterization of the High-Shear Low-CAPE (Convective Available Potential Energy) (HSLC) Tornado Outbreaks (TOs) in different regions of the United States. I graduated with my M.S. in Geosciences - Professional Meteorology/Climatology in August 2021 from Mississippi State University. Most of my research interests are in Severe Convective Storms (SCSs aka severe thunderstorms), although I love all things weather and climate. I created this page in December 2020 to provide local forecasts for Carroll, Baltimore, Harford, and Cecil Counties. I run this page in my free time, mostly for fun and to bring more awareness to how weather and climate affects everyday lives and activities. Posts are made at least three times a week, with many more during active weather patterns. I also do hyper local weather forecasts for outdoor events.

5-Day Forecast:

Today temperatures are expected to top out around 90 under partly cloudy skies. Some afternoon thunderstorms are possible, although coverage looks iffy. Right now I'm sitting at 30-40% chance and one or two could be severe. I'm personally expecting them to stay sub-severe though, and quite frankly the storms could stay to the North or South.

Tomorrow morning another little disturbance could move through bringing some morning showers to the area. I'm also sitting at 30-40% for that one as well.

High-resolution short-term models usually have poorer performance in the Summer, but this year it seems noticeably worse than normal.

The next chance for rain/storms appears to be on Monday and some models are pointing towards the potential for severe thunderstorms. I will continue to monitor.

Severe Storms Possible Tomorrow (Thursday):

I feel like this forecast is a bit of a doozy. Modeling has been terrible, but the environment to support damaging wind gusts is there. Currently there is a slight risk (2/5) across the region, but storm coverage looks iffy. Right now I'm sitting at 30-40% chance of storms between the midday and afternoon hours.

It's possible storms could miss to north or south and the area sees nothing. This is a tough forecast, but maybe tomorrow morning will help clear the air for the forecast.

Thursday Thunderstorms Update:

Thunderstorms look possible to probable on Thursday (50-60% chance). The SPC has issued a day 3 slight risk (2/5) for severe thunderstorms. The main concern appears to be damaging wind gusts at this time.

I'm not sold on them being severe but we'll see how things shake out the next couple of days.

5-Day Forecast:

Today temperatures are expected to top out in the mid to upper 70s under mostly sunny skies.

Tomorrow temperatures are expected to warm-up a tad, with some morning cloud cover. There is small chances of some isolated showers mainly between 7am-1pm (15-30% chance). I might actually make a quick update post on the potential for showers/storms tomorrow morning because chances look like they're trying to increase based on latest models. Either way should be a nothing burger...just some isolated showers with possible rumbles.

Thursday I'm still keeping an eye on the storms for that afternoon/evening and into Friday morning. Some could be severe, but I'll wait to get more specific, since models have shifted more towards non-severe thunderstorms.

Severe Thunderstorm WATCH Issued:

A severe thunderstorm watch is in effect until 11pm.

The main concern is damaging wind gusts up to 70 mph and frequent lightning. Some isolated large hail and a tornado or two also appear possible.

Severe thunderstorms update for Today and looking ahead to more storms

There is a slight risk (2/5) for severe storms today. The primary concern is damaging wind gusts although some isolated hail and a few tornadoes also look possible. The highest chance for storms is between 6pm-12am.

Please have multiple ways to get warnings and be weather aware.

I'm also keeping a close eye on Thursday for the potential for severe storms. The SPC has put a day five, 15% risk for the Mid-Atlantic region. This 15% risk is equivalent to a slight risk (2/5).

Today temperatures are expected to top out around 90 under mostly cloudy skies. It might start out as partly cloudy but clouds will roll in as thunderstorm chances increase.

There is a slight risk (2/5) for severe storms today. The primary concern is damaging wind gusts although some isolated hail and a few tornadoes also look possible. The highest chance for storms is between 5pm-12am.

I'm also keeping a close eye on Thursday for the potential for severe storms. The SPC has put a day five, 15% risk for the Mid-Atlantic region. This 15% risk is equivalent to a slight risk (2/5).

I will likely have more information about severe storms for today...later today.
