I’m a third-year atmospheric science student at Cornell University who has been blogging about the weather since 2011. While I’m not officially a meteorologist, I have accumulated a bit of experience forecasting both local weather (in western Maine and New Hampshire) as well as national/international weather during my time writing for and I also have experience programming in Python, teaching concepts in weather forecasting, and communicating forecast information to general audiences.

New update on weekend storm

I have just looked at the models, which are very split on a track solution for this system. The GFS is putting the storm well to the south of New England. Another model the WRF has it slightly farther north with accumulations of a mere inch. The most potent  solution  is the ECMWF which has a extremely powerful low in the gulf of maine with substantial snow along the coast. We will keep tuning the forecast.

Stay tuned!


Storm update

The snowy storm expected to hit thursday night is amounting to something. The snow will accumulate to >1″ at the coast with 1-3 in the Maine foot hills and 2-4 on the upslope sides of many maine and New Hampshire. The storm forecasts for sunday are still being tuned. At this point we can expect some rain and wind at this point we can not tell how much.

Tropical trouble

The tropics are up to no good again. The only named storm in the atlantic basin is hurricane Rina with 105 mph winds however I think that this is very conservative and it is more likely at cat 3 status with 115 mph winds. Also in the atlantic basin is an area of disturbed weather (97L) the nhc is saying that it has a 20% chance I would put the odds slightly higher at 30%.

Stormy week

Well Just as I have started to experiment with this blog I will have a lot to talk about. There was a cold front that passed through last night and will be touching off some brisk NW winds. This will cool things off. That is step 1 in the sequence of unsettled weather. Step 2 includes a strong low passing to the south of New England on thursday into thursday night. With the cold air in place from the front yesterday we very well might get some snow late thursday/thursday night. Step 3 includes a direct hit from a very powerful storm possibly with tropical origins on sunday but this is really far out so we will have to keep fine-tuning the forecast.

Stay tuned
