Freezing rain can never "see" directly freezing rain, rain or snow on weather radars, Doppler or conventional. However, it is possible to estimate the area covered by freezing rain with radars indirectly. The intensity of the radar echoes (reflectivity) is proportional to the form (water or ice) of the precipitation and its diameter. In fact, rain has much stronger reflective power than snow but its diameter is much smaller. So the reflectivity of rain coming from melted snow is only slightly higher. However, in the layer where the snow is melting, the wet flakes still have a large diameter and are coated
Alexandria rainy winters and moderately hot summers that, at times, can be very humid; January and February are the coolest months, with daily maximum temperatures typically ranging from and minimum temperatures that could reach .
