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.

Severe Storms Update for Today:

Today, most of the region is under a marginal risk (1/5) for severe thunderstorms. A small part of northeast Harford and most of Cecil county are under a slight risk (2/5) for severe thunderstorms. The main concern is isolated damaging wind gusts and isolated large hail. The storms are expected to be widely scattered to numerous (70-80% chance) with the highest chance for thunderstorms between 4-10pm. 

I probably won't be able to cover the storms today if things get hairy because I have a lot of native perennial plants to plant in the front and backyard of the house.

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

5-Day Forecast:

Temperatures are expected to top out in the mid 80s under partly cloudy skies. Rain/storms are possible this afternoon with what's looking like a 50/50 shot for most. The highest chance for storms is between 2-9pm. There is technically a marginal risk (1/5) for severe thunderstorms, with the concern being the off-chance of damaging wind gusts. I'm not too worried about it right now, but might update if things change.

Saturday there also appears to be a decent chance of rain/storms. Accompanying the rain/storms will likely be a cold front...which will probably bring quite mild temperatures from Sunday through the middle of next week.

5-Day Forecast:

Today temperatures are expected to top out in the upper 70s under partly cloudy skies. Temperatures are expected to stay between 80-85 the remaining four days of the forecast. A little warmer than I was hoping, but it looks like it could cool off on Sunday back into the 70s.

5-Day Forecast:

I'm wondering the lows people saw this morning because some models were pointing towards lows around 50F.

Today temperatures are expected to top out in the mid to upper 70s under partly cloudy skies. The theme of high temps between 77-81 and low temps between 55-62 are expected to continue through the end of this five day forecast time frame.

I'm keeping an eye on the potential rain on Thursday accompanied by a cold front because depending on how the models shake out...the region could see a continuation of the pleasant "fall-like" temperatures. It'll technically be meteorological fall, but not astronomical fall until the equinox.

5-Day Forecast:

Today temperatures are expected to top out in the upper 70s to around 80 under partly cloudy skies.

Rather pleasant conditions are here to stay with the five day forecast showing temperatures between the mid 70s to around 80...with overnight lows in the 50s. I'm also not seeing any big chances for rain.

It also does look like the more mild temperatures could continue through the first week in September.

Go out and enjoy it!

5-Day Forecast:

Today temperatures are expected to top out in the low to mid 80s under mostly cloudy skies. Some scattered showers (40-50% chance) are possible this afternoon and through the overnight hours. Good news is this potential rain will bring with it the cold front I mentioned. Temperatures the middle of this week will fell very nice and pleasant before a slight warm up late this week.

5-Day Forecast:

Today temperatures are expected to top out in the mid 70s under mostly cloudy skies. Isolated showers (20% chance) are possible today, but shouldn't pose any threat. It will be windy because of Erin, which is well off the east coast. Even though Erin is so far away, it is pulling winds towards the central low, which is going to result in primarily NE winds today. So, yes, I'm expecting winds to be strong out of the NE with mean winds of 10-15 mph, and gusts up to 25 mph.

The next chance of rain I'm seeing is for Sunday, where chances look to be between 50-70% right now. It looks like showers and storms between the afternoon and overnight hours. The good news is that after the rain/storms moves through a cold front will follow and bring below normal temperatures through the end of the month of August (Per CPC and model data consensus).

5-Day Forecast, Erin Update:

Temperatures are expected to top out in the mid 70s under mostly cloudy skies today. Today will feel nice compared to some of the days over the last few weeks. Temperatures will continue to stay relatively with daily highs between the mid 70s and mid 80s expected.

Not much has changed with Erin. Erin is a category 2 hurricane with 110 mph winds. Erin might get back to major hurricane status in the next couple days. The Outer Banks region of North Carolina is under a tropical storm watch because it could still get tropical storm force winds and some rain from Erin.

5-Day Forecast, thunderstorms update, Erin update:

Today temperatures are expected to top out in the low to mid 90s under partly cloudy skies. Isolated to scattered thunderstorms (40-50%) are possible this afternoon and evening. There is also a a marginal risk (1/5) with the afternoon/evening storms, where there is the off-chance of damaging wind gusts.

The area will then see a nice cool-down with low to moderate rain/storm chances over the remaining four days.

Erin was a category 5 for a brief period of time and has now weakened to a category 3 capable of 125 mph 1-min winds. Erin is expected to maintain major hurricane status until late Tuesday or into Wednesday. She's still not threatening any US land, so still nothing to worry about.

Major Hurricane Erin Update:

Dang, Erin has rapidly intensified over the last day or two and it now a high end category 4 hurricane with 155mph winds. It's still not threatening the east coast, but will be cool to watch with all the tools at my disposal.

I wouldn't be surprised if it gets upgraded to category 5 soon. Some recent data just came in showing 10-sec wind gusts of a 170kts or 196mph. One of my friends from grad school is on the next flight going in, and she thinks it's category 5.

Edit: whoops Erin was updgraded to category 5 with 160 mph over well an hour ago now. NHC hasn't updated the figure I attached below but released a special statement saying Erin is category 5. Sorry for the confusion.
