>>> on our website tonight we have posted a brand-new list ranking the areas of the country that are the worst for people with seasonal allergies. of course, there's still snow on the ground in a lot of places, and in others people are already suffering from what we were warned would be a mean allergy season. our report tonight from our chief medical editor dr. nancy snyderman .

>> oh, my god, it's death to me because i'm like oh, my gosh, i just want to have like -- put something over my face.
>> reporter: at the atlanta allergy and asthma clinic, it's busy.
>> we are definitely seeing more patients having difficulty with these higher tree pollen counts.
>> reporter: from here to the cherry blossoms in washington, d.c., rising temperatures mean pollen from trees and flowering plants, and allergists say this will likely be a bad season.
>> we're seeing earlier spring season , and late-ending fall seasons. this is problematic in certain parts of the country, in particular where the pollen season starts as early as january.
>> reporter: every year, allergists rank the most difficult places to live if you have spring allergies. the worst city this year, jackson, mississippi. but northern cities are increasingly on the list. with buffalo, new york and detroit, michigan, in the top 30. some are pointing to climate change. one study last yearlinged the nation's rising temperatures to increased pollen counts, and a longer allergy season.
>> rising temperatures also lead to a later end in allergy season. and this is the time of year we really see the pollen count go up. and in the southeast so far this year, it has been wet, and that leads to more plant growth.
>> reporter: experts recommend for those suffering to see an allergist now, before the season gets worse. and to help diminish symptoms, take your run in the morning, shower at day's end to get rid of pollen on hair and clothes and keep windows closed and pets indoors. bracing for an allergy season even before it heats up. dr. nancy snyderman , nbc news, new york.
