Hi, this is meteorologist Steve Pelletier and I am the Weatherman. Thanks for checking in to theweathermanpodcom on your Wednesday. It is the 18th day of the month of September, a month that still continues to keep it dry up across the Northeast. But first let's take a look at the pollen. We haven't talked about ragweed and grass pollen and overall pollen over the last several days, being that basically it has been almost stagnant. From the central and northeastern corner of the nation it's been dry. So whenever it's dry like that, you tend to have a continuation of high or very high pollen counts, very high ragweed extends from all of Texas all the way up to the Great Lakes and then high amounts across through Pennsylvania into New Jersey, new York and into southern New England. That looks like it'll continue until we get some soaking rains. Now the storms that were moving into the coast gave lots of rain to north and south Carolina. Well, that's gradually drifting north but also pushing just offshore, so that means it may not be that much rainfall across the mid-Atlantic or the northeast corridor from DC up to the Boston area. Dc better chances of rain, as will be Baltimore and Philadelphia. However, as you get up to New York City and up to the Boston area, it looks like most of it will be on the dry side for the daytime on Wednesday into Thursday. Then it looks like a dry pattern does reestablish itself across the Northeast and much of the central and northern portion of the nation for the next several days into this upcoming weekend and this weekend, the start of autumn officially on the 22nd on this Sunday, when it passed 3 o'clock in the afternoon, the autumnal equinox and it changed the seasons from summer to fall and it has been trending cooler. Most temperatures across the mid-Atlantic and northeast have been about two degrees below normal Rainfall, well above below normal. We saw only about a tenth of an inch of rainfall in many communities from DC to Boston area and that may change with some of this tropical moisture, but for the most part it does look dry.

Speaker 1:

Here's a look at the weather situation if you're traveling on Wednesday at the airline hubs across the nation Looking good in Atlanta, charlotte, just a few light showers. Might be some showers in DC and Baltimore and Philly, but only light amounts of rain in New York and up in the Boston area as that storm shifts further offshore it does look dry across much of Texas, louisiana, central Mississippi, river Valley and St Louis. Northward to Chicago. Looks like some rainy weather moving into Minneapolis, st Paul. Also dry conditions in San Diego and L Louis. Northward to Chicago. Looks like some rainy weather moving into Minneapolis, st Paul. Also dry conditions in San Diego and LA, but it looks like some rain moving into San Francisco. Dry conditions from Seattle down to Portland, south Florida also under scattered showers and thunderstorms during the afternoon and early evening. No major areas of moisture. That's going to be affecting travel across the nation on this Wednesday. Looks like everything shifts a little bit further offshore as we head towards Thursday and Friday. Some dry conditions, central and eastern portion of the nation.

Speaker 1:

Well, the forecast for your Wednesday calling for mostly cloudy conditions across the northeast corridor and the possibility of some showers. 76 to 80 degrees expected highs. A chance of showers on Wednesday night down to about 65. More chance of showers on Thursday. Thursday's high 76. Friday partly sunny. Might be a shower, but it looks like drier trend near 80.
