ifstream giving me trouble

im using fstream to get visual studio to read a file with about 100 lines of repeated info, just different values every line. Im using a count variable to keep track of how many times this is read, but it keeps saying 0. i know the file is being opened because i placed an If statement to check for me. and yes the file im reading from is also the location of my cpp file. If you could take a look and tell me what im missing i would appreciate it!

#include<iostream>
#include<iomanip>
#include<fstream>
#include<string>
using namespace std;

int main() {
//file variables
string date;
int rainIn, minTempF, maxTempF;

//variables
int count = 0;
double totalRain = 0;
double averageMinimumTemp = 0;
double averageMaximumTemp = 0;
double overallMaxTemp = 0;
double overallMinTemp = 0;

ifstream inFile("2014WeatherData.txt");

if (!inFile) {
    cout << "Error: Input File Cannot Be Opened\n";
    exit(EXIT_FAILURE);
}

//read file records
while (inFile >> date >> rainIn >> maxTempF >> minTempF) {
    count++
}

cout << count << " Records read\n";

return 0;
}

im only in computer science 1, so im still learning any feedback will be very much appreciated!! also here is a few lines from the txt document im trying to read from

20140101    0.00    69.08   31.10
20140102    0.00    42.98   25.16
20140103    0.00    51.98   25.16

The problem is that...

int rainIn, minTempF, maxTempF;

...creates integer variables, and you try to read floating point values into them. Change them to doubles. (You also need a semicolon after count++).
